I think a lot of the problems occur through bad or little preperation, as with any painting job prep is all!
having said that i have tried and tried with Hammerite -finished job looks good but just doesnt take the knocks , any good coach Enamel should stay on and last if preped and applied properly-allways use it
never have probs with it , thats my experience anyway,
If you go to Halfords and ask for a TIM guage it is the right size to fit defender dash, and comes with a selection of senders 4/5 course thread fine thread, and its the right colour =black 26.00
hope this helps,
