I've been sandblasting different parts of my Goat with "black beauty", but I'm not sure if I should use it on the insert for the hood scoop, and the housings for the tail lens. Specifically, the "fins" of the scoop (not the technical name, I know, the horizontal "bars", if that's a better explanation) are what concern me. I blasted the rest of it, and that part is fine. The tail lens housings seem like a lighter material, so I want to be sure before I go forward.
Any suggestions, as always, are appreciated.
