Got a painting question if ya don't mind .
I'm painting a 1466 . This tractor sat outside for years in the whether . I steamed cleaned it , sanded and used Scotchbrite on it . I only primed the bare spots thinking where the old paint was solid I wouldn't need it . When I was painting today I've never saw so much fish eye in my life . And BIG , looked like the size of a dime .Original paint was IH and I was shooting 2150 over it . I finely gave up and just flooded it with paint . This is a working tractor but it would have looked better with out all the runs .
Any guess what caused the fish eye ?

fish eyes are usually caused by a contaminate like a silicone product, or oil. could have come from the soap cleaner if used with the steam jenny, or another source is in the air lines. if the compressor is passing oil vapor, or if a line oiler was ever used on the air hose that would be a good place to start looking. do you have air iine filters and a water trap on the air lines? if it fish eyed that bad, i'd look to the air supply with oil.

Forgot to say it did not fish eye where I primed .
Didn't use any soap in the steam cleaner . Never had a oiler on my air line . This is the 5th paint job this winter and no problems except a small place on a battery box , witch didn't supprise me .I have a big filter 25 ft from my compressor . I just finished painting some other parts tonight and no fish eye in them . Just one of those things that makes me scratch my head lol

Did you sand it and then wipe with thinner ?? Only had that problem once and that was when someone used some penetrating fluid while my buddy was painting . Made him so mad . He took lacqure thinner and washed the whole tractor down and started all over . We always primered everything and on sheet metal it got wet sanded with 400 before painting .

I painted a Massey 135 for a friend last summer. He'd occasionally wiped it down with oil over the years to keep the faded, oxydized paint looking a little better. After sanding, wiping with laquer thinner, and quite a bit of priming, I shot the paint just to end up with massive fish eye like you describe. After 3 failed attempts to get a decent finish, we finally had to resort to stripping the sheet metal all the way to bare metal and starting over. Seems the oil was imbedded in the old paint.
