Polishing and waxing a Vanagon is such a thankless task that I never do it.
But, I am going to change my ways.  To make the job even bearable, I have
decided to buy a power polishing tool.  The last time I had such a thing in my
hands, it was a tool borrowed from a body shop and I recall that it required a
delicate balance between applying enough pressure to get the compound to work
effectively and applying too much pressure resulting in it working too
effectively.  The thing seemed to be constantly asking,"Should I burn through or not?"

My question:  Do the orbital polisher/buffers (WEN for one) work effectively
or should I buy a low speed 7" sander/polisher?

Thanks,
George
