Looks like fisheye, although I’ve never worked with that product.

Definitely fisheye.
Something is contaminating the wood and doesn’t work with the finish.
Did you spray silicone on anything even close by?
Did you use a tach rag, if so what kind?
Is the paint acrylic?
Plus it looks to be sprayed pretty heavy.
Lighter coats would be better.
A lot of times I will spray a very very light mist coat and let it tack up good then spray regular coats after that.

+1 fisheye/craters

WB acrylics can be contaminated with wax, oil, and silicone.

I’ve used that paint airbrushing ghost flames on small stuff. Would never use in it large area. Dries really fast, and required a lot of thinner using many light passes. If it dries on your spray tip, you can blow gelled chunks of metallic that create similar looking defects; but have never seen any that large?

Metallic’s are more sensitive than other colors. They require flawless surface prep and significant skill to lay down uniform coating.

Did you get same defects on your practice pieces?

You have to thin the ever-loving snot out of that acrylic paint, and make a lot of light coats with a lot of time space between coats because of the water content. I did it once with a project, and I will never do it again. It took a long time to clean the paint out of my airbrush, too. I don’t remember what the project was, any more, but I sure remember the fun with the clean up.

If you are using a air compressor you have water and maybe oil get in your lines . When was last time you drain the water out of your compressor.

Trap? Sounds more like Rich paranoia meds run out?

Intention was a reminder, and attempt to help if test samples were different.

Either he didn’t practice the finish schedule, which means he should of sprayed test samples using same process, or he did something different on final application?

Sanding that acrylic down is PITA.
Wish Steve luck finding the problem, and fixing it.

Never used their metalics, but have sprayed quite a bit of the Folkart and other cheap craft acrylics (matte and gloss) without any problems. What were you using to thin it?

Cheers,
Brad

It was a joke. I’m not surprised you didn’t get it. Now, who’s paranoid?

I usually thin my acrylics with a silicone/wax mixture, makes them nice and smooth.

Thats exactly what I did. I mixed up a new batch put some IPA in it. Did some very very light coats and they went away soon as I tried a thicker coat they came back so many light coats…
