Hey team, i'm restoring and adjusting a few G1 junkers i have lying around and most of them need a repaint. I've been using automobile touch up paints and they just don't seem to stick. They scratch easily and chip with minimal movement.
What paints are the best and how do you go about getting them to stick.
Ive been preparing the area by removing all the old paint, then sanding with a 120 grit sand paper. I then apply a grey base coat and then 2-3 layers of the colour i've selected. Is this correct?? Do i need to apply a clear coat as the finishing touch? Will this method work on plastics also?
