After a while the paint is gonna come off because the scooter hits the ground and stuff. On my headtube/neck I sanded it down major then put the bondo in the unneeded holes and sanded a bunch more, than put on primer and then sooo many coats of paint, I wasn't in a rush so I'd just go out into my backyard and spray paint it a few times a day, I'd say at least 10 coats.
