If it's a random orbital, you're fine...if it's a variable speed, you better know what you are doing, or no more clear, no more paint.
I gotta correct ya here bud, there's 2 types of Variable speed polishers/buffers, Dual Action and Rotary. D/As will NOT burn paint no matter how heavy the compound or how long you leave it in one area. Rotarys on the other hand WILL burn the paint.
Bingo.
I have a Meguiars random orbit (rebadged porter cable) - does a great job. I'll get to see how it works really soon..........damn wife scuffed her bumper on my truck's bumper this morning.
I too have the Megiars G110, however, its not a Random Orbit its a Dual Action. Random Orbits are the Wal Mart "waxing Machines" you see for 30 bucks that look like a steering wheel with a bonnet on the end.
The way i was always taught was to let the weight of buffer do the work. Some areas that have stubborn water spots or light scratches that wont seem to leave, you may have to apply a little force but not too much or you will burn the clear coat right off. With that said, Keep the pad wet with polish, compound, etc.. Too much is never enough! Which in turn will keep the pad and the clear/paint cool. Also start off on the lowest speed. you shouldnt have to get over 2 or 3 if its a 5 or 6 variable speed buffer.
Edit: Dodge Clear and paint is very THIN! so be careful.
Not nesc. true, when doing initial passes with product, you are supposed to apply (< 20 total lbs) to the surface your working, as to get a good cut on the paint. After initial buffing/compounding you then take the pressure away to finish the paint and remove any micro marring that may have been made due to initial cut.
