Lemon Pledge and such is a take off on an old detailer's trick.
Cars going to the auction the ones with crappy paint, scratches,oxidation, blushing, etc.
We could make em look like new with Lemon Pledge or the old stand by, engine oil.
Little bit of oil and a buffer, filled in and covered the problems. Just long enough to get it through the auction. First wash job and the problems were back. The oil, not only engine oil but the oil in Pledge fills all those micro scratches and such and gives the illusion of a nice clear finish.
A buffer works wonders, just like on those cloudy headlamps you see.
BUT, unless you know what you are doing with a high speed buffer, don't.
Just catch a wool bonnet in something and you can have the buffer rip out of your hands and do some real damage to what you are working on. Lot's of destroyed trim, and antennas come to mind, when the pad grabs em. Not to mention your wrists when it snaps out of your hands.
Also if you stay too long in one spot the heat from the friction can burn the compound into the plastic or even distort/melt it.
If you are going to attempt buffing, go slow and be careful. Mask off everything you don't want covered in compound, it's bugger to clean out of a soft top, and makes those dang zippers even more fun.
An orbital buffer may be a better choice if you are new to buffing. Less chance of catching on something or damage if it does. But an orbital will take longer to work out the scratches and such. But heck you got time.
