well the sanding has started and my fears have eased, The Yellow Film works very good with plenty of control of the rate of sanding and lasts a suprisingly long time. I had no problems removing varing degrees of orange peel and even a few minor runs. I am running the da at 25PSI wide open, I have a 6" and 3" pad for it, I also have a small 2" DA and a 1" orbital denib.
I really like the 2" since these early coupes have allot of raised body lines and so many areas that are to risky to sand with a 6". I have 2,3 and 6 polishing pads to shine things back up. I bought the Flex 3" rotory, but have not used it yet. Its allot bigger and heavier than I expected though, bigger than my 4.5 grinders but with all these variable speed polishers, they seam to have larger bodys. I am sure because the rotors need a bigger OD for more torque at low rpms. I will use my B&D ELU for the 6" pads though
One last question, I really like the dry sanding is there any advantage to the wet sanding besides longer life from the tolex and buflex pads?
