A comment about power buffing: Power Buffing came from the old days of enamal paint
that would oxidize and loose its shine. Using a abrasive compound brought back the shine
at the expense of removing some of the paint.
Today, the paints are entirely different in that they rely on the clear coat to provide the shine.
The clear coat is about 1/2 the thickness of the paint so it is fragile and won't take abrasive
buffing without the danger of going through the clear coat.
The power buffer is heavy and the pad is also, so too much pressure can be applied very easily.
This will damage the clear coat. The reason shops use a power buffer is that it is fast, not good just fast.
Save your paint and use the least abrasive cleaner as possible and only apply it by hand.
