I've been using JBWeld and have been happy with the results;
not happy that the tubes seem impossible to reseal, completely.
Any other products with which folks have had success?
Absolutely.
PC-7 and PC-11 are great. And there's no need to buy a new PC, only
the glue.
I would buy it in a pair of 4oz. cans. Ace Hardware has that size
iirc. If you use separate popsicle sticks or separate screwdrivers
for each can, and never let any of one touch the other, I've gone 20
years on the same 8 ounces and the unused stuff looks like new. ( Most
of my repairs are small. I haven't been doing as much gluing in the
last 10 years (plus I also use 5-minute epoxy in the syringe.)
I'm not sure of the difference except the first is dark grey and the
second is white. I think the second was labeled for marine use, but
the first is water-resistant I think, also. Still, they must know
something. So if you need to glue a marine, use PC-11.
PC-7
" Two-part multipurpose epoxy adhesive paste works as a bonding agent,
sealant, and filler for a range of indoor and outdoor applications
Bonds many materials, including fiberglass, wood, concrete, many
metals, brick, glass, ceramic, and rubber
Seals oil, gas, and water tank leaks, as well as plumbing and masonry
cracks
Fills holes, castings, and molds
Application temperature range is 35 to 115 degrees F, and service
temperature range is -20 to +200 degrees F
PC-7 formulation provides extended working time, for large and
critical jobs, which allow the user to reposition work or make
changes.
High "wet grab" or tack of PC-7 Paste Epoxy makes overhead and
sidewall work easy, without drip or sag. [it sagged for me, but if
I'd waited 2 more minutes before I put it on, it wouldn't have. Better
to put it on early and keep pushing it back where it should go.]
Note: PC-7 will not bond to wax paper, Teflon, Polyethylene and some
other plastics. Test a small area when in doubt."
PC-11
" Two-part marine epoxy adhesive paste bonds materials in dry, wet,
and underwater environments. Bonds many materials, including
fiberglass, concrete, many metals, glass, ceramic, and rubber
Can be used in indoor and outdoor applications, with a temperature
range of 35 to 115 degrees F and a service temperature range -20 to
+200 degrees F High-tack paste can be used in vertical and overhead
applications Resists mild acids, caustics, detergents, gasoline, fuel
oil, and fresh and salt water"
They are not as drippy as JBWeld, and can be smoothed with a wet
finger. (Tastes terrible. Use the next finger.)
It sticks to glass, aiui.
My first occasion to use one was a dripping drain pipe below a
dripping faucet. I didn't feel like fixing everything so I only did
what was essential, the drain, and even though it was dripping water
while I worked on it, PC-7 still hardened and was waterproof.
Incredible. It takes about 5 minutes to harden, and it would droop
while i was waiting, so I'd push it back up, and eventually it
hardeded while it was up, in good contact with much of the pipel
In another case, I was missing the cap for a wine sack. I coated the
threads with vaseline and molded a cap from PC-7. When it hardened, I
drilled a hole for a string to tie it to the wine sack. I'll admit I
never use the thing, but it's still good 40 years later.
Another time I had a commercial grade food mixer, and the teeth were
damaged from one fiber gear. 5 were missing. I put a lump of PC-7
on the area and when it dried, I carved teeth in it. It only ran for
a minute, before one or more teeth broke, but I think that's pretty
good Little teeth under a lot of pressure, even the originals broke.
I also patched a sauce pan, and then forgot and boiled all the water
out of it. It still didn't leak.
