I have embarked on re-finishing my OEM wheels. Since I had a flat one day and I took the wheel off, I decided to clean it (might as well). I've used Goo-Gone (I knew that it would "take" paint off) which worked well on the BACK not FRONT. It wiped a bit of the paint off the back which is alright, it was dirty anyway. I have then used 0000 grade steel wool to clean all the grit and build up. Then pressure washed the wheel and wow! I am still detailing the small imperfections and will post detailed pictures here!
