I want to repaint my bike. Can I use paint thinner to remove the paint? Should I use urethane paint to repaint or what? Anyone have experience with this?

Your paint job will never be any better than your preparation, equipment, and materials. The only time I got a result I was really happy with using spray cans, I used lacquer. I've not been successful in finding lacquer in spray cans since then.

One other bit of advice: A tube has four sides. I'd recommend finding something made with tubing to practice on before you try to paint a bike frame. Bicycling Magazine, sometime in the early 70's, had a WONDERFUL article about painting bike frames with spray cans. If you can find it, it contains more practical advice than you'll find anywhere else.

To remove the paint you should have it "media blasted". They use a softer material than sand, and it comes off nicely with no damage to the fragile tubes.
I have painted one frame and I had much of the necessary equip, like a HVLP spray rig and a shop with a homemade booth. I didn't have any dreams of a fabulous job, because I'd heard that spraying frames is difficult. Let me tell you it is a b!tch to do it. Taking it to an auto painter is no better. They always think that they can do it , but they have trouble too. If you dont believe it, buy some 1" dowels and position them to resemble a frame as close as possible and do a little practice. You'll see what I mean. Powder coating would be an alternative that you might want to consider. It is relatively inexpensive for a one color job. Check the yellow pages, and ask lots of questions.
Good Luck

I've painted several frames now and don't think it is so hard. The round tubes allow the paint to flow in different directions which helps to eliminate runs. I wouldn't bother trying to paint using spray cans however, the quality of the results will not be worth the effort. As far as how to paint goes, the prep steps are identical to thoes of painting a car with the exception of media blasting (note: the media can be sand) to give the surface some tooth for the paint to adhere to. Go to a local library and pick up some auto body paint books and contact your local auto paint retailers and ask for some tech materials published by the various paint manufactuers. Good luck.

There's a reason that having a bike painted costs more than having a car painted. It's not easy. I have a friend who was a pro racer and sprayed his favorite steel rig to match whatever team he was racing for that week (and of course, sold the frame the team gave him). His bikes always looked awful- but he pointed out that he could do it himself ten times for every one time it was done professionally.
