I used different materials each time, but it both cases it was high quality automotive paint and primer, applied with a spraygun. I removed most of the old paint chemically, and finished with and old knife and sandpaper. The first frame was primed with zinc chromate since it had some chrome plating. The main base color was Dupont Chromabase metallic blue, and I finished with several clearcoats. I don't remember the materials I used on the second frame. It was a different primer and base, but still good quality materials from the same store. I painted it in the autobody shop of a friend.
