I painted this little Millrite mill when I rebuilt it last year. I stripped it down to bare metal which entailed peeling off a ton of filler used to smooth the castings.
I used oil based enamel paint, thinned 10% with mineral spirits as several writers have recommended, sprayed it using a Binks HVLP gun with 35 psi on the gun and 5 psi on the paint pot. It does need a pressure pot in my opinion.
I've used several paints. I like Rustoleum. I think it atomizes best and self levels to the smoothest finish. I haven't used a primer or a hardener. It did take much longer to dry on the aluminum pieces compared to cast iron. The cured paint seems nice and hard to me.
Mostly I spray mineral spirits based polyurethane on wood. I find it harder to get paint through the gun and that paint hangs better on vertical surfaces without sagging.
