The car was primered with what I beleive is a urethane primer (typical grey, nice and smooth, not rattle can).

Prioer to painting, I did some bondo work on a few areas I wanted to smooth out and I tossed a little rattlecan primer on top of that. Once everything was dry, I first sanded it all with 150 and then followed it with 320 grit, I washed the entire car down with simple green and used a brush to scrub everything, then I let it dry and wiped it all down with a rag and mineral spirits. I waited a few hours to make sure everything was dry and I started rolling on the paint...

That was the extent of my surface prep. Maybe the paint made for California is different?

I do have some spots on my hood that I had to sand down to bare metal, so I'll check that out once I finish painting the hood to see if it sticks better there.

I'll take some pictures of the scratches but they look exactly like Exit1965's.
