I have been fighting a problem with fish eyes in a painting project on a new univair lift strut, I used variprime and 2 part epoxy on try 1, so I stripped the variprime off of the factory red primer, put on more variprime, a different 2 part epoxy...fish eyes again, so stripped everything down to bare metal. Fresh variprime, a little bit of fish eye in the primer, after wiping with lacquer thinner, xylol, and acetone. Let the variprime dry overnight. Off to tractor supply for some of their Majic brand enamel went on like glass. Nice stuff. Now I just hope it doesn't chip off when I install the strut... I have almost 8 hours in a stupid lift strut. Cleaned everything with acetone and lacquer thinner, was still having problems, bought a water desiccant filter didn't help either...but the enamel worked good. Tim

I had the same problem with a new Univair lift strut that I got last year. I think it is related to that red oxide primer they use.
Wiped with lacquer thinner too.
I finally gave up and let the fish eyes stay. Will fix some other time.
Tractor Supply Majic paint is on a lot of parts on my Kubota B21 and it has been great. I suspect that you will have no problems.
I used their hardener with it.

Several years ago I was doing some work on my 1950 John Deere B that I use to mow my runways. I bought some tractor supply spray cans of John Deere green to spray the parts including the replacement used hood. Sadly, after 3 or 4 seasons here in the deep south Texas sun, the parts I painted with the TSC John Deere "greene". turned Blue.
Since then I repainted with John Deere green that I bought at the local John Deere dealer and it is holding up well and has not changed color.
I don't recall the brand name on the TSC stuff, but it sure disappointed me.

What I've seen cause that is scuffing before degreasing, and leaving a contaminant on primer a long time. Primers are porous, so they tend to absorb contaminants and really give us problems. I fought a similar problem and figured out that I'd scuffed it first to rough it up and by doing so had ground the contaminant in deeper.
The TSC paint is most likely a Polyurea paint. That's some good, tough stuff and they're pretty forgiving of contamination. All in all, good stuff.

I restore old classic cars and have some experience with refinishing problems. The worst culprit that causes fish eyes is silicone polish that had been used over the years..and of course..oil/grease residue.
To prevent fisheyes it is important to wash the surface with soap and water followed by a good rinsing. And followup with a final prep solution found at any automotive paint stores. Even then fisheyes may appear at the beginning of the first spray coat! As soon as fisheyse appear stop spraying add a few drops of anti-fisheye in you spray gun cup. immediately apply a light spraycoat on the fisheye area and they will flow out and disappear. But better yet I always add anti fisheye drops before spraying as a preventive just in case. NAPA auto paint sells anti fisheye called Squirts by Martin-Senour. Also auto paint stores that carry Nason paint have anti fisheye products. For finishing struts and metal cowling I use Nason Ureathane auto paint with catalyst.
