How to Polish Sportbike Frames

time2011/10/11

polished water sport bike frame will look like chrome. In order for the frame to look shiny and glossy, it has to be perfectly smooth. This do-it-yourself project will take the better part of a weekend, since you should take your time and work methodically to make sure that you polish every centimeter of the frame.
Sand the Frame
Sand the frame with an orbital sander. You need to start with wet 320 grit sandpaper. Make sure that the sandpaper and frame stay wet any time you are sanding. You can sand the crevasses by hand. Make sure you get the entire frame. Turn the frame as you work so you can sand all of the frame.
Continue to wet-sand the frame using 400 grit sandpaper, followed by 600 grit sandpaper, 800 grit sandpaper, 1,200 grit sanpaper and finally 2,000 grit sand paper. With each new water sport bike, you should remove the scuffs and scratches made by the previous grit. Take your time to ensure that all imperfections are sanded out. By the time you finish sanding with the 2,000 grit sandpaper, the frame should be as smooth as glass.
Buff the frame using the orbital sander. You will need an automotive buffer pad and a brown cutting compound. This will polish the frame. Wash the frame with dish detergent and allow it to dry.
Polish the frame using the orbital sander, a clean polishing water sport bike and a red or rouge cutting compound. Once you have polished the entire frame using the red cutting compound, it should be very shiny, almost like chrome.
Wipe off the frame with a flannel cloth to remove smudges.
