Take some pictures too!

Not sure if you are addressing to me or to DJ Delorie.

Anyway, I haven't applied the final coat of wipe-on-poly yet because I
was waiting for DJ Delorie's reply on his method of rubbing
wipe-on-poly. Well, I guess he is not going to reply, and I will have
to use another method that I found in this newgroup, and I will do this
in this evening:

o Yesterday, I sanded the surface down very smooth to remove the
dusts
that landed on the coat of wipe-on-poly that I applied the other
day.

o This evening, I will run the air cleaner for one hour to remove all
the dusts.
Then, I will apply two thin coats of wipe-on-poly on the surface
in
quick succession. I plan on waiting for one hour between coats to
let
the poly to dry to touch before applying the second coat. I will
_not_
sand between coats. After two coats, I will wait another hour and
then
use wipe-on-poly to touch up areas that are not shiny -- again, no
sanding before applying wipe-on-poly to touch up.

Hope this will finish this refinishing project that has been going on
for one month.

FWIW Jay. After you run the air cleaner, let the shop stay still for two
days. This time will give the dust that was circulated by the air cleaner
time to settle. Make certain that you use a tack cloth before the next
coat.

Sound like I started putting on the last coat too soon after I had run
the air cleaner. And wipe-on-poly didn't dry that fast in the unheated
basement. These two factors resulted with me having dusts on the wet
wipe-on-poly.

I will not correct this until X'mas is over and I can leave the poly
some time to completely hardened (let's say one month). Then, I plan
to light sand it and try rubbing finish. Hopefully, this will be good
enough. But if I end up sanding through the three coats of thin
wipe-on-poly, I may have to apply a thick coat of poly and wait another
month and try rubbing finish again.


I'm a little puzzled as to why you're having to put this much work into
wipe-on polyurethane. Just sand smooth, wipe on, let set for the
recommended time, repeat until you're happy with the finish. No elaborate
dust-control measures needed.

Sounds like wipe-on poly just isn't the right finish for you--spend the
$125 for a gallon of precatalyzed lacquer and a Woodcraft HVLP gun. Dries
hard enough to sand in 40 minutes or so, not enough time for it to pick up
much dust, and you can sand and polish it as bright as you want.
