I am a novice at buffing as I just painted the car using BC/CC system, and I have been buffing the clear coat. My advice is the get the right tool for the job. I bought a Harbor Freight variable speed buffer. I also bought the backing plate with the foam pads. I tried to use a hard rubber backing plate with a lambs wool cover, but it burned thru at an inside corner. Use the right foam pad and keep the spped slow. IIIRC, keeping the speed under 150rpm is safe. Its a little slower than running at higher speeds, but far safer. You don't want to burn thru the paint at this stage.
