I don't know
thing is, during last summer, when I still had my 335i, I used to do it sometimes 3-4 times a WEEK
I used to put the PC in speed 1 and just slowly wax it
I had no problems, thing looked nice
felt nice, to me
but what do I know, I'm a supernoob lol
I plan on getting a new car real soon and I want to do it right
and yeah...
