I am painting some parts for a tractor and having trouble with fisheyes in the paint. they are in the same place every time. I have sanded down to the bare metal in some places, and wiped down everything with reducer and thuroughly cleaned every thing with plenty of time to dry and used clean towels my paint is mixed right. I have a warm area to paint in, I have tried diffent pressures even adjusted the gun for different thickness of paint and still the fish eye's come back to the same places

what can I do?

Clean everything with degreaser/dewaxer. Reducer is not a good cleaner. Then add some fisheye remover to your paint.

I have the same problem. My next paint job, I'll use Fisheye eliminator. House of Kolor calls it Krator Eliminator.
