Restoring vintage 3Rensho road frames
I recently restored two vintage 3Rensho aero road frames, one a 53cm and the other a 58cm:
When I originally acquired these frames, the smaller one had a pink paint job and the larger one was purple. Both were quite worn, with many scratches and some rust as well. I decided that I would completely restore the frames myself. While I’ve painted at least a dozen frames and wrote a tutorial on the process, I’d never before tried to fully restore a vintage bike, complete with decals.
After documenting the original decals, I sandblasted both frames. Then I laid down several coats of primer / filler from Duplicolor, finishing with a layer of white primer so the top color would appear brighter. For the main coats, I used three cans of Duplicolor “Perfect Match” automotive spray paint on each, with Barcelona Red Metallic for the large frame and Blue Streak Metallic for the smaller one. I let each frame cure for a week, then wet sanded any drips and touched them up. Painting with spray cans is difficult because they have an unpredictable output and despite my best efforts, it’s almost impossible to avoid drips.
After the paint had cured an additional two weeks, I applied the decals. I bought the decals from “Global Bicycle Decals,” a UK-based seller on eBay. These are reproduction decals printed on vinyl, and lack some of the quality of nicer water-slide decals, but are much easier to apply. After applying the decals, I clear-coated the frames using two cans each of Rustoleum’s automotive clear. Again, because of the sub-par flow from spray cans, I had to wet-sand a few drips and re-apply a fresh coat of clear. The end result, however, was gorgeous! The metallic paint has a lovely sparkle to it, and the clear brings that out even more.
Overall, I’d say it took me 15-20 hours per frame to restore them, and about $180 each in paint supplies, decals, and sandblasting costs. Financially cheaper than having a pro restore them, but when you factor in the time, well… let’s just say it’s not a good business plan.

And thank you for the honest assessment of the savings (or lack thereof) by doing this yourself. Now that everything's cured, do you feel like the paint will be as durable as a "pro" job?

Incredible looking restorations! I love that 58cm and am thinking it would sure look good in Texas!

Very nice! What most may not realize is the difficulty of painting a bike frame is the absence of flat panel surfaces, all curves and bends, angles and pinches. They are difficult and often frustrating.

You're quite right - it takes practice and "can control" to lay down even coats and avoid drips. And even with a lot of practice, the cans themselves do not have an even flow / output the way a professional spray gun system has. Inevitably you have to do some wet sanding of drips in between coats to get a truly flawless finish.
