Hey MisterX, When I had my BMW I looked around Richmond and found that Advanced on broad street downtown is about the only place that does that around here. The way that it is normally done is to put a heat gun on the paint to make it more pliable, then they gradually roll out the fender using the machine that you linked to. What width tires are you going to try and put on?
I know I'm replying to a thread that is 7 years old but here is some fender roller info:
Roller made by Eastwood MFG. There is a u-tube video out there of it being used.
I am renting it and a heat gun from esetuning to give it a try on my 2002 WRX wagon that is Eibach Pro lowered and I just got some 245 18 inch tires. BTW - these things are ludcrisously wide. I don't know why discount tire direct said they would fit.
