I have an old scooter (1967 Lambretta if any of you want to know) with a single stage repaint. It started cracking in some places. I know i cant fix that, but how do i keep it from spreading? Should i "feed" the paint with some #7? and then seal it in? i have no clue what to do. The scooter is in perfect shape and it sucks that the paint is cracking. Anybody have any suggestions? Ill take pics of it when i can...hopefully soon..
