On my trunk lid i get these marks that look like rust, and dirt but dont wax off, also unget the rear wiper is a yellow line from the oil or lube used in it. Does any one else with a pepper white car have this problem? If so how do you take it off?

 

I get the rust marks on my LY. I use a clay bar and that gets most of them off without too much work.

 

The "rust spots" supposedly clay off, I haven't tried it yet on my spots.

As for the stain from the rear wiper, I'm waiting for answers here: https://www.northamericanmotoring.co...224#post607224
