I dont have any pictures but ive already sanded it back down. i primed it with 2k filler primer and sanded it down dry with 320. After that i cleaned it with grease and wax remover, tacked, and sprayed. Im ready to shoot it again but im afraid it will do it again. Btw Im fairly new to this so any suggestions would be helpful.

you need to really clean it down with degreaser, your getting fish eyes from the left over residue of any spilled gas, did you degrease it before you sanded and sealed it? if not sand it down again and degrease the ***** out of it. also you can add a fish eye stopper to your paint and clear, ask your local distribuitor. and drain the water out of your air compressor and lines.

hope this helps you out.

you could also be getting water through your line. Do you have a water/oil filter on your compressor?

I would suggest against FEE as it will cause more problems,

Try using A-Jax and lots of water instead of wax and grease removers.

There is a way to check with water if it's good to go,,,

check this link, the picture shows a problem, what looks like clear is water http://www.a2zautoforums.com/showthread.php?t=2838

was looking.. They indeed appear to be coming from under the paint as opposed to water out of the gun on top

if you set up your gun on a piece of clean masking paper every time before you spray something (like you always should) .. you can catch moisture/oil vapor problems before you waste paint. after you finish spraying something its a good idea to do this again.

If you get fisheyes on your paper, then its your air supply.

just on the panel, then it's your prep work.



ajax, or comet with a brillo before painting anything like engine bays, tanks, etc. then rinse good, wax/grease remover and it should be clean for sure.

I've even started using comet on entire car bodies before even touching a piece of sand paper.

on a recent paintjob....I had a nightmare with fisheyes in my clear......
I contributed this to armor all... it was a hyabusa (mototcycle) that was always armor all'd...
Normally, I clean with ajax, then purple power, then wet sand....... some people will wet sand first... not knowing they are burying the waxes into the surface, which will always come back to haunt you.......
Anyways.... I had about 200 or so fish eyes....
after a few hours of drying... I mixed a cap full of clear.... took a paint brush, and filled in the fish eyes, I made a second and 3rd pass, after flash times....
Next day, wet sand with 2000, and buff.....
in 20 years of painting, this is one of the coolest tricks......
I had alot of airbrush work on this job, so, repainting wasn't by 1st option..

why wax and grease remover again?
(that's probably the problem)
you didn't grease or wax it since right?

Why would the wax and grease remover contribute to this?

i think i figured it out.

I recently bought a used sata jet 90 which i used to spray the topcoat. When I got it, it was dirty and the air piston was sticking. So i cleaned the gun an then i sprayed a little oil around the air pistion on the gun. I am thinking the oil got down into the gun and is now spraying out in my finish.

are you talking about the needle/piston that the trigger pulls back? There's actually a lubricant designed for spray guns with a vaseline like consistency that you can lube that piston with, and it won't get all over the inside of your gun.
