That was my thought... Petroleum getting in the paint... WD40 or other light lube on the gun? Oil from compressor in the lines? But, I'm no painter, only done 2 projects do far and haven't had any fisheyes
**Photobucket sucks**

I would have to agree with the oil particles or products of combustion getting into the paint. If that is not the case and your place and tools are free and clear of that stuff, I would think it would have to be a reaction with the prior paint on the part. Is this happening with a bare metal piece or when you are applying the color over the primer?

go back to wax and grease remover, it dries slower so you put on wet with one towel and dry with another,stuff that dries too fast doesn't let you wipe the contaminants off. you could be leaving contaminants during sanding that the degreaser won't touch, such as a hand lotion/cleaner you might be using, the source of fisheyes can be frustrating, some one spraying armour all or wd from 500 feet away can do this. Have to be more specific,over the whole panel, isolated areas, over primed areas?
What filtration do you have on your compressor? You useing a dessicant drier at the gun also?

Agree completely. Also make sure you are not spraying Armor-all or similar products anywhere near the paint booth. That stuff is fish eye city.

I'm sorry to say that I'm an ultra amateur, but in this case, it simplifies troubleshooting, because I'm talking about rattle cans. (see attachment of previous project car, rattle cans aren't THAT bad for small areas...) Different cans, different types of paint, sometimes paint, sometimes even the primer fisheyes. There's definitely no Armor All being used. I think the suggestion to use the grease remover and then wipe it off is probably my next step. I use a lot of acetone or alcohol, but it does evaporate quickly, so it may not be working. I'll give the grease remover a shot next time I'm painting and report back. Thank you very much.

Unless you are having them specially mixed by a jobber those rattle cans are not really compatible with the factory paint on the car.
I have a feeling you already know that.
I totally agree.

Fish eye, If your using an air compressor make sure your oil does not have defoamer in it. It usually is Silicone based and sprays in the air when compressor is running. They add it to oil.
he's using rattle can paint,not spray gun and air compressor

First step to a better finish is to stop using acetone,because it leaves film and it also can re-active,break down the substrate,use prep solvent,wax & grease remover. Second, some products are just not compatible,especially when applied very heavy.But you have to be seriously doing something wrong when you manage to have fish-eyes with rattle can paint. 
I agree with this also the reason the wax grease remover and or prep takes awhile to dry is you apply it and then wipe it off with a second clean white rag while still wet so you remove what was dissolved

...One thought is to make sure the compressor is'nt sending any oil/contaminants through the line...Even a small amount will cause big troubles... Are you heating the garage ??? Could be some type of airborne contaminants related to that ...What about the gun ??? Good and clean ??? Used any lubricants on it ??? Depending on what you're spraying you can add the fisheye eliminator but you'd be masking the real problem and it may not even do the trick depending on what the trouble really is...
