Marzocchi called the early paint 'tangerine dream'. I'm getting nowhere finding a code for that.
Not seen a RAL thats close yet and certainly not the metallic effect! Normal flat RAL should be readily available from my powder coater so might go down that route, should be more durable than normal paint I suppose, but would be a right pain to keep the internals from getting coated.
Im off to the auto paint shop today to pick up some cellulose paint for my dads project car, will take the fork with me and see if they can do anything to help.
