Alright, I want to try and spruce up the 500E. It's charcoal grey. I was going to a friends house the other day and when i arrived i noticed i had tar on my trunk. Not having bug and tar remover, i removed it with an extremely small ammount of rubbing compound. Well, it left very light swirl marks. And that is enough to annoy the crap outta me. I was wondering if anyone can suggest something to remove them. I waxed the car maybe 3 weeks ago. What do you guys think?
