Thanks - yes, I was planning on doing 2 coats of unreduced epoxy before sanding. Which grit range would you sand this with, to end up with a nice smooth 600-grit finish for base? Could I just run 600-grit (wet) over it? I guess it depends how well the unreduced epoxy laid down...If you sand a single coat, it's highly likely to have multiple sand-throughs unless you are doing texture reduction and nibbing only. Two is the minimum recommended for sanding.
Sometimes it's possible to briefly knock the tops of the texture off with something slightly coarser, like 320 or 400. This will save time and sandpaper, since the very top shiny layer of epoxy tends to load fine sandpaper. You have to be careful, though, and stay away from edges and body lines.Thanks - yes, I was planning on doing 2 coats of unreduced epoxy before sanding.
