I've never really been sure what's the appropriate way of bringing out the best in the plastic areas of cars? Specifically I'll be buffing out a '93 300ZX TT and it has the factory tail and bumper. Are these done by hand or machine and what with?
 
Plastic has a much lower rate of thermal conductivity than metal, so it absorbs heats at a far greater rate. Keep the machine /pad moving and use a light pressure
 
Yeah. TOGWT hit it perfectly.

Bumpers retain heat and can really heat up the paint making a blemish worse. Start by hand then machine with no pressure.
 
I wouldn't hesitate to ue a machine (even a rotary), just keep the difference in thermal conductivity in mind and don't overheat things.

Sorry to butt in, but would using Ultimate Compound by hand on the White Plastic area of the Toyota Camry be a mistake?

Never worked on a Camry, but I sure wouldn't expect it to cause problems.



While the paint on plastic parts is often a bit different from that on the rest of the car, I never think of/experience it being any big deal.

As Accumulator mentioned,



I treat painted plastics the same as the rest of the car, just be mindfull that plastic can heat up quicker. I have also found the the plastics tend to clean up quick and easier than the painted panels.



If your using a DA you should have no problem at all.
