I just finished putting the first coat of epoxy on my hull. (this is my first stripper). In some areas I can see lighter color blotches on the dark red cedar strips, which I would guess is glue that didn't get sanded off. Should I wait 24 hrs. till the epoxy hardens and sand that area again ? Or just till the epoxy is cured enough to attack the spot with a cabinet scraper ? When I get around to sanding the deck should I be able to see these areas by wetting out prior to using epoxy ?
