My GTA has always had small half circles of black around the holes for where a front liscense plate once was. I really haven't tried anything yet, but I was wondering what would work to remove the marks?

Also, I accidentally got a pen mark on my leather. What would take that out as well?

Any info would be great and appreciated.

 

I am curious as well.

My front nose sort of warped where the plate was, anyway to fix this?

And for the pen mark, maybe just get some dye and try to go over it that area.

 

On the half circles, you can try some color match wax and see if that does it. If the paint is gone, touch it up. On the leahter, try some leather cleaner/conditioner. If it;s "perminant", go to an upholstry shop or a detailer and see what they have.
