Have any of you ever painted a bicycle frame?
My son needs a new bike (he's too big for his current one) but they are RIDICULOUSLY expensive. I'm thinking of buying a used bike cheap and repainting it. I've been reading some threads on bike forums, but none really give any great advice. Tell me what you think of "the plan":

-Find a cheap bike without too much rust and working parts.
-Rough the frame up with some sandpaper
-Prime it with a black primer (spray)
-Cover it with 2 coats of a black glossy spray
-Cover that with a coat of clearcoat for protection

My son is 8, soon to be 9, and I know he's going to knock this thing around. I don't expect it to be unscratched/dinged whatever. Do you think this will hold up pretty well to a normal 8-9 year old's riding habits?

Any advice is appreciated...
