Does anyone know of a good repair for a vinyl dash.

 

Vampire damage or rabid raccoons?

There should be someone in your local area doing this sort of repair, or should be since that was/is a growing trend considering the cost of replacing a complete dash pad.

I'd check local yellow pages or call several auto upholstery shops---they'd know who's doing this, might offer it themselves.

 

I think there's no good DIY solution for it. I would bring it to a local upholstery shop instead.
