    help me win a debate.

    c'mon, if you're spraypainting a frame, you sand first, right?

    want: risers, light, stiff, 1", black if that can be

    Well, you actually strip a frame, whether of rust or of paint. It needs to have a clean surface to adhere to. E-mail Doug Fattic, Joe Bell, or Bryan Baylis and they'll tell you what's up.

    Sanding is bare minimum. Sandblasting is where it's at.

    If the original paint is in good condition, just sand it so that the spray will stick to it. That leaves a nice primer (the original) underneath to help with rust control.

    Don't forget to sand again after it dries, then clear coat. Then dry, then another coat of clear, then wax, and polish.

    I would sand the original paint, it will hold better than most primers you can put on with a can.
    I'm not one for fawning over bicycles, but I do believe that our bikes communicate with us, and what this bike is saying is, "You're an idiot." BikeSnobNYC

    Hey probably just heard someone say that it's best paint over the original paint, but didn't realize that you have to sand the original paint a bit to get good adhesion. You have to go down to bare metal in areas where chips and scratches go that deep though.

    the order of things depends on how you want to the outcome to be and how good the current paint job and surface are. But YES you do need to sand.

    If you want a really pretty finish you will wet sand every layer of primer, and every layer of paint but the last one. For show finishes, they actually sand the final layer with super fine paper to give it a mirror like finish, then rub it out with like 3 grades of polishing compound. For a decent looking spray-can job I would probably do two coats of primer sanded in between with 320, and 2 or 3 coats of paint, maybe sanding the first coat with 320 0r 400.
