overspray right? and the light housing on the decklid too? remember?
For the overspray on the wheels I would use a SMALL amount of paint thinners on a rag - maybe try the back of the wheel first to see if there is any reaction
I would use TCut on the light housing - its a kind of "Cutting compound" so just rub it in like polish, You will feel it removing the "Rough spots" just don't go too mad
Then remove it the same as polish with a clean cloth - Then when its CLEAN just re-polish the area and you will see the difference
