I have a 15 year old Weber Genesis Gold gas grill. Overall, it's in very
good shape. The burners, flame spreader bars and stainless steel
grills are in good shape. But the outside parts that are painted black
has weathered. So, I'm going to spray paint it and hopefully it will look
real good again. A similar new one would be $600+, so I think it's
well worthwhile. The hood and front doors below are stainless and
still look good. But I'm considering painting those red or green for
a different look. So, what needs to be painted for sure is the lower
black metal cabinet that doesn't get hot and the black firebox and
edges of the hood that do get hot. And optionally a color for the
hood and doors.

So far I'm headed towards Rustoleum High Heat in flat black for
the firebox and edges of the hood. And Rustoleum Semi Gloss
regular paint for the cabinet. Here is the interesting and weird
part. Looking at reviews at Home Depot, most people are reporting
that the high heat product works, but there are many that have had
problems, ranging from what is supposed to be black looking gray
or the paint not adhering, even though they did extensive and
apparently correct prep. And all those negative reviews get a
response from Rustoleum saying that their high heat paint needs
to be cured at like 400F for an hour for it to work properly. And
every one of those posters points out that it does not say that on
the product instructions on the can. This has been going on for
years, no further explanation from R. It certainly has lowered my
opinion of Rustoleum. Every person that has any problem with the
paint, that's the answer, basically it's your fault, you didn't properly
heat cure it, even though nowhere except in the HD reviews does
R tell you that you need to do that.

I also find it hard to believe that it really
needs to be cured at 400F, because without that on the can, there
would be like 90% failure rate. That's because most people would
think it could be applied anywhere, not just high temp locations and
part of plenty of applications would never get much heat. You would
buy one can of high temp paint and use it on other parts too. On the
other hand, looking at high temp paints from other suppliers, I see
that there are ones that are ceramic based that do require high
temp curing. But those spell it out in the directions.

So, IDK, very confusing. I think I'm OK because the high heat product
will go where there is considerable heat and the rest I'll do with
regular paint. That was kind of driven by the fact that I think a
flat looks OK on the firebox, but I want semi-gloss on the cabinet.
If I decide to paint the stainless hood red or green, I'm looking at
Duplicolor high temp auto paint as that's the only decent colors,
reg, blue or green that I can find in high temp product.

So, any experience or advice ? What do you make of R and the
heat curing, but it's not in the directions?

The idea of heat treating something implies a kiln. Otherwise the
heat treatment would be uneven. Who owns those?

Exactly. You could use your oven if the parts are small enough to fit.
If you look at auto high temp paint, that's what they suggest, if the parts
won't get hot in the application. So like brake calipers, you could put those
in your oven. And then for various parts that you can't put in your oven,
who knows how hot various parts actually get in a car or similar?
Like painting a pipe, one end could be a much different temperature than
another. And so far I haven't seen any supplier give more information,
like what are the downsides to it not curing properly, will it peal off or
will it just be less durable, etc. Less durable is far more acceptable than
if it peels off. Lots of questions, no answers. But Rustoleum is something
else. Any complaint at HD, even that it's gray instead of black, stock answer
is that you didn't heat it to cure it, even though the can doesn't say anything
about needing to heat it.

With the gas grill I'm comfortable that the firebox part will get hot enough though
and the cabinet parts I want to paint with a semi-gloss anyway, so that's not an issue.

You're right, it's in the technical data sheet:

DRY & RECOAT TIMES
Sprays: Dries to touch in 30 minutes and to handle in 1-2
hours. Allow paint to dry for 1 hour before heating. In
order to achieve full cure, the coating must be heat cured
at 450ºF for one hour. Product may emit smoke and
harmless odor.

On the can it has exactly the same, without this one key sentence:

"In order to achieve full cure, the coating must be heat cured
at 450ºF for one hour."


Quite stunning that despite this going for many years, it's still this way.
Puts R way down on my list of good suppliers. But like I said,
it's impossible that not heating it leads to some obvious failure in the
short term. The vast majority of people using a high heat product will
just read the label, not go find the TDS. And there have to be a lot of
applications where people spray it both on areas that get to 450F and
areas that are not heated at all. How does one get 450F, even on all
parts of a gas grill firebox without a kiln? The top, no problem, but the
bottom? Supporting parts, etc?

Paint it a combo of CCP red and yellow and DNC blue.
Did you think to look up the directions for the paint on the
internet? It clearly points out the multi-step heat cure process.
You're right, it's in the technical data sheet:

DRY & RECOAT TIMES
Sprays: Dries to touch in 30 minutes and to handle in 1-2
hours. Allow paint to dry for 1 hour before heating. In
order to achieve full cure, the coating must be heat cured
at 450ºF for one hour. Product may emit smoke and
harmless odor.

On the can it has exactly the same, without this one key sentence:

"In order to achieve full cure, the coating must be heat cured
at 450ºF for one hour."


Quite stunning that despite this going for many years, it's still this way.
Puts R way down on my list of good suppliers. But like I said,
it's impossible that not heating it leads to some obvious failure in the
short term. The vast majority of people using a high heat product will
just read the label, not go find the TDS. And there have to be a lot of
applications where people spray it both on areas that get to 450F and
areas that are not heated at all. How does one get 450F, even on all
parts of a gas grill firebox without a kiln? The top, no problem, but the
bottom? Supporting parts, etc?

Project update. I've got all the paint figured out:

Firebox - Rustoleum High Heat Black, Satin/flat

Hood Outside - VHT Caliper Paint, Red

Cabinet frame - Regular Rustoleum Black, Semigloss

Wheel hubcap, - White gloss, can of old marine enamel I already have from the boat.

The Rustoleum HH is supposed to be heat cured at I think it was 400F.
The VHT is supposed to be heat cured at 200F. I easily do the VHT on the
hood. The firebox, most of it I can probably get to 400F, not sure about the
lower parts, but it will be what it will be.

Only did the hubcap so far, came out great. Have to get going or probably
delay it a month. Tree pollen will be coming down. I decided to take it apart
to paint it, at least that's the plan. Looks like 1 bolt holds the firebox, it was
badly shot, I snapped it off and that end now lifts free. Other end has two
bolts that hold the burners in. Thanks to all for the advice, I'll post again
on how it comes out.

So I had some time to work on this. I decided to take it mostly apart, eg remove
the firebox from the cabinet to be better able to paint it right. I was surprised
how easy that was. Only three bolts. Two hold the burners in, those nuts loosened
right up, burners came out, they are in great shape. The other bolt was on the
other side and it holds the firebox to the frame. It was badly rusted, is sheared
off. But that allowed me to remove the firebox. I soaked the remains of the
bolt with PB Blaster, waited a few hours and I was able to loosen and remove it.

I progressed to the first paint operation, which was to use the VHT Caliper Paint
on the hood and doors. They say to do two light coats followed by a med wet
coat. Recoats are to be done within an hour or after 7 DAYS. 7 days? And after
painting it needs to be heated to 200F for 30 mins to cure it. So I tried to do what
it said. It was windy, was forecast to be windy for like the next several days and
tree pollen will be coming down soon, so I decided to do it in the basement.
I set up a halogen work light, but even so, lighting was far from what it would have
been outside, where you can see much better. As I was putting on the medium
coat, coat number 3, there were spots that looked glossy, others that looked
flatter. I tried putting down more paint, didn't seem to change it that much.
At that point, I didn't know what was going on. Was this just one area drying faster
than another and it would even out? Put on more paint? But then I was worried
about too much, runs, etc. They always tell you that several light coats are better
than one heavier....

It didn't matter much at that point because I only had one can of paint. It claimed
to be enough for 15 sq ft, at this is just a medium size gas grill hood and two
front doors for the cabinet. But at this point, I was almost out of paint, not
enough to do a heavier coat on the whole thing. So I stopped and waited to see
what happened. Which was mostly nothing, it dried about how it looked. Some
spots rich, glossy, others dull looking like a satin finish. More surface looking
satin than glossy. My conclusion is that even though this was supposed to be
enough paint for 15 sq ft, it needed more paint. I'm hopeful that one more heavier
coat, getting it all wet looking, is the solution. The good news is that the color
is awesome and it doesn't look like I have to fix it, start over, etc.

But then there is the usual lacking information on the instructions and how to
proceed. As noted above, it says that after being painted, to achieve full cure
it needs to be heated to 200F for 30 mins. Nothing about having to wait to
do that. It also says that to re-coat you need to do it within an hour or else
wait 7 days. I've never seen 7 days before for anything, usually it's 24 or 48 hours.
The issue there is that if you do it quickly, the coats behave like one when
drying/curing. But if you do it beyond that, the first coat is partially cured and
the fresh paint on top interferes with it curing correctly. So you have to wait
until the first coat is fully dry/cured.

With current scheduling I have no need to do anything for at least 3 days.
So the question now is how to proceed? I see a few choices:

A - Wait 7 days, then re-coat, let dry and then cure at 200F.

B - Cure now, wait 7 days, then re-coat, let dry, cure again.

C - Cure now, re-coat anytime, which would be at least 2 days from now,
3 days from first coat, cure again. Figuring that curing accelerates
the process, so it's cured, no need to wait 7 more days.

Opinions?

I have a 15 year old Weber Genesis Gold gas grill. Overall, it's in very
good shape. The burners, flame spreader bars and stainless steel
grills are in good shape. But the outside parts that are painted black
has weathered. So, I'm going to spray paint it and hopefully it will look
real good again. A similar new one would be $600+, so I think it's
well worthwhile. The hood and front doors below are stainless and
still look good. But I'm considering painting those red or green for
a different look. So, what needs to be painted for sure is the lower
black metal cabinet that doesn't get hot and the black firebox and
edges of the hood that do get hot. And optionally a color for the
hood and doors.

So far I'm headed towards Rustoleum High Heat in flat black for
the firebox and edges of the hood. And Rustoleum Semi Gloss
regular paint for the cabinet. Here is the interesting and weird
part. Looking at reviews at Home Depot, most people are reporting
that the high heat product works, but there are many that have had
problems, ranging from what is supposed to be black looking gray
or the paint not adhering, even though they did extensive and
apparently correct prep. And all those negative reviews get a
response from Rustoleum saying that their high heat paint needs
to be cured at like 400F for an hour for it to work properly. And
every one of those posters points out that it does not say that on
the product instructions on the can. This has been going on for
years, no further explanation from R. It certainly has lowered my
opinion of Rustoleum. Every person that has any problem with the
paint, that's the answer, basically it's your fault, you didn't properly
heat cure it, even though nowhere except in the HD reviews does
R tell you that you need to do that.

I also find it hard to believe that it really
needs to be cured at 400F, because without that on the can, there
would be like 90% failure rate. That's because most people would
think it could be applied anywhere, not just high temp locations and
part of plenty of applications would never get much heat. You would
buy one can of high temp paint and use it on other parts too. On the
other hand, looking at high temp paints from other suppliers, I see
that there are ones that are ceramic based that do require high
temp curing. But those spell it out in the directions.

So, IDK, very confusing. I think I'm OK because the high heat product
will go where there is considerable heat and the rest I'll do with
regular paint. That was kind of driven by the fact that I think a
flat looks OK on the firebox, but I want semi-gloss on the cabinet.
If I decide to paint the stainless hood red or green, I'm looking at
Duplicolor high temp auto paint as that's the only decent colors,
reg, blue or green that I can find in high temp product.

So, any experience or advice ? What do you make of R and the
heat curing, but it's not in the directions?

I would call Weber. I had a problem with the squirrels chewing my hose. They
sent a new hose with a "squirrel guard" (spring) on it for free.
