Can someone please please tell me what I did wrong? Put on first coat a day ago and going to put second coat on but started to wrinkle up.
Sprayed with highly diluted **** and span and wiped and dried off the area before applying 2nd coat.
I tried to wipe wrinkles with tac cloth which well only made it worse but it was wrinkled anyway before.

I don't understand why it did this the first coat of spray paint looked great but the second is a disaster :/

go on youtube and watch paint society his name is brian he gives the best information on how to do all types of paint jobs on cars he works at an acura dealership
I second this, brian has helped me out a numerous occasions with my car's work. He's really what led me to painting my car myself in my garage. His videos are really easy to follow, its crazy to think that his gig at Acura is only a part time evening thing. He's main career is teaching (as you can tell by his videos presentation.)

I sanded the factory paint down some with 320 then 400 grit. Cleaned the surface with mineral spirits then spray painted and got fish eyes and runs everywhere.
Silvia sounds like I am having your same problem. So i assume you cannot even sand and use the factory primer then either ?
Also if I paint the bumpers does that also need to be sanded down to the plastic thereby starting all over there as you suggested on the panels that are metal?

I would try a test panel on the plastic. But I’m sure it’ll be fine after just sanding. On the body itself around the rear quarter panel and pillars, I got that reaction. I stripped everything off. Metal etch, primer, sealer, paint, and clear.
You didn't put on a new primer? Yea probably be best to use new primer and stuff. Don't know what's underneath and if paint work has been done before.

I took the piece off in between rear bumper and the hatch door. I think gonna wire brush that to bare metal and I have some 2 in 1 primer filler can apply before trying to spray paint it.
I also seemed have runs & fish eyes around pillars like you mentioned not sure why but I only sanded the factory paint there to get rid of clear coat.
I'm sure its the factory paint but it appears it doesnt matter seems like im gonna have strip and primer everything.
I guess ill be doing the same on the front bumper which is not gonna be a fast process.
Going to experiment some more but stripping it to bare metal is the answer I've been looking for so long. Maybe it still won't be great but if anything will work its going to be that sounds like.

Is 2 in 1 primer ok I not quite sure the difference between self etching primer and 2 in 1 primer. Both appear to be intended for applying to metal.
As long as it protects the bare metal first. You should be fine with 2 in 1.
But like others mention Paint Society has very nice tutorial videos on YouTube. I’m about to repaint my car also.

I painted the whole car (besides bumpers) with Rustoleum spray paint Lol. Seemed like a good idea at the time but now depending on how this test metal panel goes Im considering going down to bare metal all around and buying harbor freight LPHV gun and spraying the entire car at once.
I have no idea what paint to use though or if ill need a quart or a pint to do the whole car in at least 2 coats, and then theres the whole clear coat issue seems difficult to believe that someone doesnt make paint and clear coat 2 in 1.
Thinking of calling PPG and asking if they sell anything specifically for automotive applications.
What paint you planning on using?

PPG does make car paint. Go to a local paint shop and have them match your color code.
I had my car done at Maaco years ago. They used enamel-based paint. When I went to repaint my car I went with PPG Omni and that is urethane. They didn’t play well.
Here’s something I found you can read on.

I used PPG Omni as well when i painted my car. Its a good product as long as it plays nicely with the other layers on the car.

Cool I might check that out.

Anyone know where to get 400 grit circle sandpaper that fits onto drill attachment?

I bought a drill pad stick on attachment but none of the sandpaper circles are 300 or 400 grit neither Lowes or Home depot have them.

Cool I think harbor has one. If you are sanding to bare metal with a DA sander but then add primer and sand primer.

WIll you sand primer by hand because the DA sander seems like just take it back down to bare metal again.
