I've never painted a car before. I've done a ton of rattle-can work, I'm a detailing nerd who actually enjoys buffing and cleaning paint, but I've never actually laid down a coat of paint. Now, this is a cheap car for a high school kid, and the factory paint is less than great at this point, so I decided to do this the cheap/easy way.
First step was prep. For the door, I cleaned it with an APC, wiped it down with mineral spirits, and block-sanded it to rough up the factory paint. Here it is, masked off and ready to go:
Aftermarket bumper cover all prepped:
But what paint? For this job, I chose Duplicolor Paint Shop:
It's cheap, it doesn't require pre-mixing, and I can get it at any auto parts store. Applied with the famous Harbor Freight $15 HVLP purple gun:
I did three coats of color and four of clear. The results were... mixed at best:
Really bad orange peel, as you can see. I think most of that was because I didn't have a proper pressure regulator, so I was using the one built into the gun and basically guessing. Also, it was about 40 degrees, and the paint wants it to be at least 60, but there wasn't much I could do about that. Maybe in the spring I'll try and wetsand it and buff it out some, but I don't know, it might just have to be good enough. At least she doesn't have to drive around with a red door.
As for the paint itself, I'd say you get what you pay for. It's so soft I think I could honestly scratch it with a fingernail. Better than nothing, but I suspect that it's just rattle can paint in a regular can. I wouldn't use it again. by the time you do all the prep and masking, it's not worth it to use cheap paint, IMO.
