Tab if you make it back here... I got a chance to use the Rupes today. I'm not really doing anything that requires paint correction and have only used it to apply Adams liquid paint sealant so I really can't comment on its correcting ability, although I'm reasonably sure it should outperform the Porter Cable.
But as far as usability I highly recommend you retire the Porter Cable to the bedroom. The Rupus hardly vibrates at all and I used it one handed 90% of the time either by the handle where the trigger is or just holding the body above the buffer pad. Doing the same task with the Porter-Cable my fingers would have been asleep.
Well today its going to get used. I have new paint on hood bumpers and front fenders where they blended the silver. Its been 3 months as of yesterday. So hood and fenders is going to get paint correction and then entire truck a coat of LPS and then patriot wax. I just stripped washed it and dried it off. Taking a break and then going to drag this bad boy out.
