Backyard Hack
I’m not an expert but I don’t think you are getting the increased adhesion that using reduced epoxy sealer does. Hopefully Barry will weigh in.Bumping a month old thread...sometimes when I've had those craters, they are superficial enough that I can just sand them out.
It might be overkill, but I always shoot unreduced epoxy and wet sand the entire thing with 600 (because I'm usually spraying metallic), then shoot base. When you're less than perfect like me, 600 gives you a perfect substrate for base, allowing a chance to remove all dust nibs, any minor peel, and any little craters that might have happened.
