Might as well tag onto this post.
After much fun (!@#$%^&) drilling and taping the broken studs on my car I have to ask what the finish is on the front. Pic here to show part number and that I cleaned off the back under 25 psi glass ball while the front was taped off.
The SAAC forum says stuff like shiny but not too shiny. This is like saying semi-gloss (I have come to hate that non-specific term)!
Any help on where I end up? Is this like 1500 wet/dry shiny?
Also, how many surface imperfections are allowed? This is not the finest aluminum casting I've seen so are the pinholes in mine from corrosion or simple porosity? There isn't any on the main overall surface (like you see on an aluminum framed window).
