polish

I noodled a bit to see how I can add more of a CJ feel to the TJ with side decals. Plan is to add more polish with new wheels, 31" tires (no lift), nerf bars, and a Renegade-style decal in the orange, over the khaki. Depending on how this bit goes, I may add a polished gas cap and hood...

I picked up a Supertop that's been in storage since '13 and has this marking on the windows. I'm thinking is from the foam used on the back bow system on the Supertop frame. Is there any cleaning product I can use to remove the marks?
