Paint dimples...Please help!

[Caleb Provencio]

Not sure what I'm doing wrong, but I'm getting paint dimples that I can't stop from forming when using can spray paint. I first sanded then primered this piece of metal. When I sprayed the paint and a little with the primer, it made these dimples I couldn't stop. Any ideas on why this is happening?

That can happen when the part being painted isn't cleaned properly, or when humidity is to high or with spray paint that's been sitting around to long.

I'm sure there are other reasons and you'll probably get other responses, those are just the things I can think of.

Research paint fisheye. As Falstaff said, probably caused by a contaminant on your metal. I have had that problem when I cleaned a panel with brake kleen before. I would test compatibility of the primer and paint on some scrap metal, If they are o.k. then take the part to bare metal and start over.

Silicon particles can cause that too.

I had a die cast piece one time that no matter what i tried, it fisheyed every time I tried to paint it.

You guys rock, thanks for your help...I had no idea there could still be some greese and other contaminates even though it felt and looked like it was clean. Took some denatured alcohol and wiped them a few time and my paint went on smooth. Thanks again!

I had that happen when I painted a frame on the clothesline outside. I brought the can of paint from inside the house where it was 70f. Outside was 85f. Now I have the steel and paint at the same outside temperature and it's good.

Some people, and I've done this. Soak the paint cans in hot water for 10-15 minutes before painting, it helps. Just makes sure to dry the cans completely, don't want water dripping on your paint.

Fisheyes from oil or silicone contamination, wash part well with soap and water, wipe with any of the following solvents - acetone, lacquer thinner, rubbing alcohol.

Test a small spot first, the more aggrestive solvents may eat your primer.
