Hey everyone, I've got my 14' great auk just about ready for varninshing. I've got a lot of imperfections in the epoxy (fiberglass strings, bumps/dips etc.) I plan on doing a light sanding and then doing a skim coat or two. Would a ROS with 120 grit be too aggressive for this step? I don't think fill coats of epoxy alone will do the trick to cover up the strings and such. Also, when I do the skim coat, should I thin it down with paint thinner? Thanks

Bryan
