I use Randolph dope almost exclusively now and spray with about a 50/50 mixture. I don't worry about the blusing until time to spray clear coat. I use Brodak's crystal clear, ok I don't use Randolph exclusively, and mix 25% dope and rest thinner and retarder. The first few coats, I just give it a light mist so the inkjet decals and vinyl graphics don't mess up. After these coats, I spray a couple of wet coats to seal all decals, striping etc., the thinned clear will take out the blush. But I usually try to spray in the early morning to get away from the humidity. If this fails, I have an air conditioned shop and I bring it inside for the final coat.
