This is a roadster that I worked on Friday. It belongs to my wife's uncle. *Turned out pretty nice but man is that paint hard! I took my orange pad with SSR2 and went crazy.....hardly made a dent in it. lol
If you are having problems with correction, you may have to step up to a more powerful machine. The PC has its limits. The time saved over the course of a couple details would more than pay for the buffer.
