modern waterbased paints are so much softer than the paints used on older classics, or even cars from 10 years ago (my '98 Rover Cabriolet that is on long term loan to Dad just does not suffer from chips, its dark blue (Tahiti) so you would see them easily if the paint got chipped)
Ref the mods Rob, its a slippery slope - Powerfolds are good though
