I'm hoping (fingers crossed) I can color sand with 1500 wet or dry in a couple days, clear it and all will be okay. I'll post pic's once I spray the bottom of the dash. I'm doing a two tone idea; I've gotta see if I like it before posting it.

I use denatured alcohol for grease and wax remover{not to drink} acetone is ok for bare metal but like you found out too aggressive for primer I let paint problems sit for at least a week or longer before fixing them.My old DuPont book says 3 weeks.I still have a lot of the old stuff stuck in my head.
