Mike, I had a winshield that I futured, put decals on, then futured again. Then I masked off the winshield to AB some flat black. when I peeled off the mask, it pulled part of the decal off, and so I had to strip the rest off (lesson well learned). Anyways, I used Alcohol to strip it the rest of the way, and it left the white fog you're referring to. I redipped the winshield with the new decal on, and the fog went away. I don't know what causes it, but I do know that wet future actually will soften the old layer of future, so they kind of mix together, which is why I think the haze goes away. I would just set it aside, and let it fully dry, before touching it up.
