Tried an etching primer on my V-Rod wheels several years ago. Didn't take, every time the wheel got bumped there was a chip in the paint to base metal. Need to strip them but took the chicken shit way out and got a second set of wheels. The bearings need replacing in the front one and I haven't been able to get it out.
It laughs at my slide hammer ID race puller. Going to have to use heat.
As bakeable paints go though I've been happy with the VHT Engine Enamel even without primer. Smells up the kitchen a bit but once done it's as durable as powder coat.
You need to look at the temp ratings of the paint first though, can't be any higher than 500°
I tried some 1200° stuff once on some steel parts, in the oven at my typical 400° and the stuff came out as soft and chalky as when first applied. Had to strip and use the lower temp stuff
