Hey Marq, thanks for the extensive reply.

First off, I didn't use any soap at all while wet sanding. Also, spray-on Gloss White Rustoleum does the exact same thing.

The patch in the picture already was sanded down to the factory paint, and wiped with mineral spirits, so I don't see how there could possibly be any contaminants.I have also tried wiping the surface down with water and letting it dry and the same thing happens.

I have learned to expect this to happen, and so I have been dealing with it. But I can't tell you how frustrating it is to spend two days wet sanding the previous coat down to glass-like finish and then having the next coat mottle up on me again.

I buffed out and waxed my hood and roof today, and they look very nice, but I see a lot of rough and uneven areas and a few roller marks I didn't sand out.

But what's most noticeable is the places where I sanded down to either the primer or the factory paint while trying to get rid of that stupid orange peel.
