Since I don't have repairs to do, do you guys think I'm OK with my 400 prep for the epoxy then paint? Or should I go a step courser like a 220 or 180? There is only one place where I'm down to the plastic itself so is there any need for a adhesion promoter before the epoxy?

With 400 my worry is whether the epoxy has enough tooth, with 180 or 220 I'd worry about sand scratches showing through. Perhaps I worry too much. Right now the plan is 400, epoxy, paint.
