So i didn't "build" a frame but i do have a bunch of parts im going to throw on a Cadd3 CanOale frame. but its paint has been removed by the guy who sold it to me. So, I need to paint this bike and I have no idea how, or where to even start researching how. I know I could get it done for 200 bucks but don't want to spend that much money. I just want to protect the frame from rust and such. If i could, I would just leave it unpainted but I know thats bad for aluminium. any suggestions as to what I should do?
