I'm using the no order mineral spirits, and it is working fine on the other panels, I think it was because the paint had been sitting for about 2 days mixed. I'm also cleaning/scrubbing down the surface with mineral spirits before paint. I'm not a newb when it comes to painting either. I've painted lots of stuff.

I did all the steps as noted. I suppose it looks pretty good, maybe I should get a scratch remover compound. That was also done with a hand cloth thingy. I can't scarth the paint off if I tried. It's hard as a rock. I told my aunt I would give her a dollar if she could scratch it, and she couldn't. Soo it's awesome stuff. Maybe I should use 2000 for final sand instead of 1500.
