I took a narsty spill on my MTB yesterday and i scratched up the left seatstay pretty well. Most of the pain is intact but there is this long white line that goes down it now. Its an aluminum frame so I'm going to assume the white is the primer. Is it possible for me to just purchase a can of spray paint and quickly go up and down the line to fill it in. Will that give me the same finish as the cheap powder paint they use on the frame. Since I dont want to repaint the whole frame what would you use to to repaint a long line like this. I dont know if touchup paint will do it right as its not just a little nick.
