I used my PC that I got about 4 months ago for the first time today!! I had to wait 2-3 months before I could do anything to it after the guy killed the rear of my car! Then, when I was allowed to wax it again, I was busy!! Anyways, with that said, I love my PC!! Although its very hard to get used to after hand doing it for soo long! I didnt have too many troubles, but I was hoping that some people could through out some advice to help me next time! Thanks!
