Looks like there is mylar (worn through) there as well (check bottom post on slingshot) . As I know where the Pinball came from he applied a whole mylar sheet over most of his PF's.
I think we will have to strip the PF Wingtip and remove the operators mylar (usually one large sheet over the top of the whole PF and the factory stuff is underneath from my experience with Pins from Ed) and get artistic. I would build up the red first to get it even and then the black .

Sounds like it could be a plan.  As far as i can tell, the bit that is worn, for lack of a swear word,  has had no mylar on it at all.
