I wont be blasting the bottom of my car or anything but I'd like to remove the undercoating "again". I did it once in the late 80's and put some undercoating back on. I usually use lacquer thinner, a scraper and lots of rags. Anyone have any tricks for doing this? Also, when I get it clean I'd like to shoot it with epoxy and then some satin black instead of recoating. Does that sound ok? Will the satin hold up to the heat of the mufflers??
