So, I've got my frame and forks, waiting on the engine, and figure I might do something while I wait. The frame/forks have a few rusty spots on them. What do you find a good way to get rid of the rust, and then how do you usually paint over it? The colour is silver/grey, but I doubt I'll be able to find a spray can that'll match exactly. Nitpicky question, but I plan on making this bike a pimper.
