Okay, I'm not hearing about anyone here getting anything sandblasted, so I'll keep that part a secret. (Most powdercoat shops will do it for pretty cheap.) Then go to the auto paint store and buy their two part epoxy primer. It comes in a rattle can and has a button on the bottom that you push to deliver the second part. Wipe any and all dust off with some alcohol. Anyway, shake the heck out of it to mix it and start with your frame, (or any item,) UPSIDE DOWN. Always do the bottom first, let it dry enough to turn over, do the top, (or the side that is going to show.) I usually hang a bike frame from wire in the garage in a makeshift paint booth. Let the primer really dry, sand a bit where needed. Most auto paint stores will eye color match any color, and you can get spray cans made of custom colors. I have had very good results with this process. You can top coat with clear gloss or satin, but vintage bikes were not really clear coated per se. Some afficionados think that the beautifully restored bikes you sometimes see here and on the CABE are "over-restored." It's your bike, do what you want with it. If you take your time and show some creative talent, you really can get professional results. I have an old Hawthorne with cool paint on the frame and fenders. The rest of the paint is rusty and gone. I'll take the bike apart carefully, clean and save the frame and fenders. (I may even do a little clear coat here too to enliven the colors.) I take a fender to the auto paint store, and he will color match it exactly. I will paint my rims, rack and chainguard to match. Pinstripe the rims, and wherever else the bike originally had pinstripes, and Voila!! I saved what I could, and renewed what needed renewing. Makes sense to me. When I get this project completely underway, I may do a biography of the process. A before and after. Stay tuned.
