Best Rust Control Paint for Axle, etc

I don't think you can get a better prep surface than what sand blasting does. The sand etches the surface really well. You need to wash the sand dust off before painting.

In 2003 I blasted and brush painted my 72 Vette frame with POR 15. It flowed out perfectly like as if I sprayed it. Looks as good today and did not topcoat it since its not in direct sunlight .

FWIW, Maybe you got lucky then. My buddy is owns his own paint and body resto shop. Swears that if you don't use the etch, then it doesn't last. And no, sand blasting doesn't etch the same way as a chemical etch does. He explained one is mechanical and one is chemical. The sand blasting leaves a fine residue of sand, almost imperceptible. So, maybe you wiped it all down with a cleaner after blasting. Either way, was just sharing what my buddy's shop does.

As for the Rustoleum, that's great to hear. I've used that before. I like how that product goes on.

Not lucky .I hot water power washed the frame and blew it off w/air. Have to get the sand residue off.
My dad blasted and painted his heavy equipment since the 50's. I picked up where he left off in the late 60's. If I wanted an automotive quality shine on some items, I would have to knock down the rough texture with a sander because the sand etched the surface so much. [Using too coarse a grade of sand dose not help ] Also paint products have changed too.

I've had pretty good luck with Zero Rust on my Mustang builds. This has been about 8 years ago though, so I'm sure there may be better stuff now.
