You can't use foam with real nitro. It will eat the foam and could ruin the finish. I emailed the manufacturer to ask.

Sorry. :-)

Listen smarty pants, I figured I would get a sense of how fast the finish builds that way! When I post the measurement, you are not allowed to read it so just skip right over that post, capisce?

Let's just step back, take a deep breath, and re-read where I used the word "THRID" , ok? :-) It was a gentle poke at one of my very good friends on the forum.

Actually I'm thankful you're doing the whole thread, Tony.

Son of a biscuit! Didn't see my own typo or your repeat of it!
Good one Dave! The thrid time is the charm!

I measured the test piece and the thickness is now .123" thick. It would appear that brushing thinned lacquer yields .001" of build per coat. Further testing is needed.

Tony I didn't think about the problem with nitro eating up the foam brush. Not a problem with water based lacquers. I bought a bunch of foam brushes from the local craft store (Micheals or AC moore). I've heard elsewhere that woodcraft has some good foam brushes but don't see where the difference would be much.

Sorry my other reply about the brushes was short, I was on my phone and it was late.
Anyway, you can definitely use foam brushes with some products, but they are not compatible with nitro. I emailed the manufacturer, as I mentioned, and they said the solvents in the nitro would eat the foam of the brush and it would contaminate the finish. THey had no opinion on how it would affect the final finish, and I didnt want to find out either! I also doubt there is a difference in quality of foam brushes.
