To make a long story short, I have brackets for the mirrors that mount to the lower windshield hinge. The paint it starting to peel and develope a little surface rust, so I took them off to repaint. When I took them off it looks like the PO had put some grease between the bracket and body. It looks like that black MOLY grease. Is that common practice/recommended to reduce any possible squeaks? Any one else run in to this?
