I have always sanded cured epoxy- and of course I end up standing ankle deep in epoxy/microbaloon dust before I get a smooth surface. Then I read this article by Rob White in 2002 WB in which he says don't sand epoxy- scrape it smooth. So I dig out the old scraper I've had for years and sure enough it seems to work pretty good on cured epoxy. I've just ordered 3 more 6" jobbers that I will try out. Any you guys have experience with scrapers you could share?
