Okay, I did a search, but couldn't find a satisfactory answer to my question. I've got 18x8", 40 offset wheels w/ 225/40/18 tires, and I'm rubbing a bit in the rear. (Not much; just slightly over big bumps.) I read the threads that said this would happen with this tire size and offset, but I went for this combo it because I got a great deal on the wheels.
Now, I know I can roll or grind down my fenders a bit, but which is the way to go? I'm not worried about structural integrity with the grinding; I'd only take a couple mm off. But I AM worried about rust; is the fender metal coated or plated with some kind of anti-rust compound/metal, or is it the same throughout? If I do grind, would be okay to use touch-up paint to cover the exposed metal, or do I need some kind of sealant or special paint?
My other option is to roll, but I'm worried about the paint cracking at the fold. How much can I safely roll without serious danger of cracking the paint? (I'll be using a hair dryer to heat the area.)
