Valve Cover finish? Correct for 1973 E series 246GTS?
I'm restoring my 1973 246 GTS 05702 and wanted to ask the forum what the correct valve cover finish is and how I might refurbish mine? Is it a paint or a texturing to the metal surface?
Years ago I started cleaning them with a scotch brite pad and they started to get a little shiney so I stopped. I believe the correct finish is not shiny, but perhaps a matte or a peened-like surface?
These valve covers have some areas where the surface looks wonderful but also some darker areas of staining and light pitting. An example is over the chain guard area, bottom right and center in photo.
