Wrinkles in my paint, how do I get rid of them.

Post by jwrape on December 7th 2011, 2:29 pm

Ok, I am spraying the hood of my 86 Fiero GT (Fiberglass). I bought another hood to paint and then swap on.
It was originally red. I sanded and cleaned with Acetone the hood and sprayed it perfectly.
Then, like a dummy, I went to buff it after wet sanding it. I burnt the paint. I should have waited.

Anyway, I got to fill the burn with a little Rustoleum Etched Primer. The primer wrickled up. I sanded it off, cleaned it again with Acetone and then tried again. Wrinckled again.
I sanded it and got all the paint off the hood back to the Red color. Clean sleight, I thought.
So I got it all smooth and cleaned with Acetone again and paint with straight Black Rustoleum again. It wrickles again.

What am I ding wrong, what is on this hood? It's only in the spot where I primed the hood. It seems to have something on it that Acetone won't take off.
I have bought some Den. Alcohol to try after it done drying and I sand it back down again, but I am getting tired of trying over and over without getting to good results I did the first time.

Help me get this thing clean.....

we really need a pic of the affected area,If it's wrinkling you may be painting over a cheap enamel respray such as what maaco uses, I would like to see a pic of this area, I'm 100% sure we can figure this out!!with all the knowledge on this forum. ahhh

After watching the video, are you spraying this hood with rusto oil base or using the spray can? if this hood has a cheap enamel respray and you are using a laqur based paint like the primer is, it appear's the paint below it is not dryed or the laquer is pulling the enamel up thus the wrinkling, this is a common problem with laquer based paint on top of a cheap enamel( what maaco uses)laquer is a very aggressive chemical it actually bite's into the surface acrylic enamel and synthetic enamel form's a chemical bond with surface, hope this help's thumbs up

Does this mean that the Rustoleum Spray Can paint is NOT oil based? I thought it was, i thought the oil base is what fights off the starting of Rust, etc...?

If I understand correctly, I should buy a can of roll on Rustoleum and paint it with a roller like everyone else?

I love the spray, it came out SO beautiful on the fender and the hood at first. It suck that it's not working.

Please verify for me and if I need to change I will I suppose. I have already started this monster project and want to get it done by January if possible. :-)

I guess I would have to go with the roll on paint all over since I know the rest of my car has a Maaco or some sort of paint on it. That's why I am repainting.

Here is my car now, the hood and fender I painted were extras I was working on before dismantling the body.

Acetone is like lacquer. It is a very hot paint. It will lift anything enamel that is not OEM or baked. I wiped down a couple of cars with lacquer and then sprayed enamel. I ended up having to sand it ALL off and start over. Good luck.
