What electrical polisher do you use?

The Porter Cable is by far the most popular dual action polisher out there.

Dual action polishers are pretty goof-proof and sell well as a result. Dual action movement is such that it's pretty difficult (if not impossible) to burn through the paint, unlike more conventional straight-cut buffers. As I've mentioned before elsewhere, I consider a dual action polisher to be more of an applicator than a buffer/polisher (not that this is a bad thing). A dual action allows you to lay down an even thin coat of product over a large area without killing your arms; just don't expect the application process to abrade serious paint defects. If your car is relatively new with decent paint, a dual action polisher will be all the "polisher" that you need.

As Herbicidal mentioned, you don't need much product when using a polisher. Work on individual sections of your car (apply/let dry/remove). Be sure the pads are clean.

I forgot to mention - watch that power cord if you use a polisher! Use plenty of slack and drape the cord over your shoulder.
