If you want something to bring back the bright factory look to ANY FADED black PLASTIC. What
I use on my Silverado, = Faded door handles,,, Rear bumper faded plastic ,,, Plastic around door frames,,, Factory fender flares, OR any faded plastic. That looks GRAY and DULL,,,,,,AND this stuff lasts for MONTHS, Does not collect dirt, Does NOT wash off, I did my Silverado 3-4 months ago and it looks like I did it yesterday. The product is " KIWI " black shoe polish. It has small sponge on the lid, Bottom line , Its a liquid shoe polish, Wipe it on and it shines. Give it a try !
