have you considered getting them professionally powder coated? They typically sandblast first as part of the process and powder coating is baked on and much more durable than paint. Lots of colors and finished to choose from...just an idea.
ok. thanks.I always had my old rims done by a powder coating company but if I was to do it at home I might try Dupli-Color Wheel Coating. It’s an acrylic enamel.
