Eastwood has a roller applied epoxy primer now. :scratchchin: https://www.eastwood.com/eastwood-optiflow-roll-on-epoxy-primer-gallon-catalyst-kit.html I'm thinking it's useful for us "shopless" driveway repairers. (To avoid spraying.) I used Eastwood's regular epoxy primer and it worked well for a novice.

I considered using it, looks fine
You can roll, brush any primer. Its not going to hurt anything . The only challanges will be getting the desired film build . That will take considerably more time rolling than if it was sprayed.
You still need to wear a mask obviously but there is obviously no over spray which is a huge bonus for the drive way jobs !
roll on primer been around for years. when I went to PPG's paint training school here in Detroit 15 years ago they had us use it. This was the ultra violet heat lamp type, which i never use or liked. Dried in like 10 minutes. LEON.
