Today was too windy and the stripper dried up before I got home from work. A lot of paint
did come off but I'm going to do a thicker application next time and I'll be sure to do the actual scraping before the stripper dries. Once it dries it seems to stop working and the paint
is easier to scrape off if it's still wet.
THe stripper that I left on the gelcoat seemed to just dry into a crust that I can wash off with a wet kitchen scrubber. The gelcoat is not glossy but I have no idea if the stripper dulled it or if it was a result from sanding before a previous paint job.
Whatever the red coating is above the gelcoat, the Smart Strip does not remove it and it does not eat into the gelcoat either.
I may just be lucky in that the top two coats of paint are really crappy paint that's easily lifted.
Verdict is "so far so good" and the claim of fibreglass-safe certainly seems valid so far. Cleanup is with water, and the safety warnings of this product are nowhere near as dire as the chemical nasty stuff.
I will report back after I do a thicker application.
