Does anyone know the official paint color for the engine covers. If you have a PET, the part numbers are 964-106-229-03 and 964-106-289-01. The covers on my latest '93 'RS are coroded and the paint is flaking off. Everything else around the engine is clean and I'd like to remove these, sand blast them, then repaint with proper color to restore them. Hopefully it's some stock Wurth paint color that I can buy in a spray can...

Also, if you happen to know the best source for this paint, I'd appreciate it.

Thanks!
