Doing some sanding today to see how this goes. I am using 320 to get it close and theni will use 400 to bring in rest of the way. I am getting it decent pics show what I have started with on the verticals to where I have it. I am bummed this epoxy sagged so much on verticals cause I love how the flats came out. Once these verticals are flattened out I guess I hit the good areas with 400 and prep for paint?
