I removed the swirls and other scratches from the metal components of my Camaro........now it's time to buff the plastic bumpers. Is there any last minute advice I should know before using a DA polisher on plastic? I know that the clear coat isn't as hard on plastic surfaces so I should keep the polisher moving. I plan on using white Lake Country foam pads with SwirlX and then will follow that up with 205. Any thoughts or advice before I begin these portions of my car? Thanks.
