A cool thing I learned from a bleepinjeep.com youtube video was how to get the sun-bleached fenders and other faded plastics back to black... take a heat gun to them.
This is how it turned out on ours. Took about an hour and a half for all fender flares and bumpers.
And BONUS! Check out how bleepinjeep did some cool DIY bushwhacker fenders for cheap in this video. We're gonna do it!
As for heat guns...
I borrowed my dad's but some time before I start pulling up the ugly old linoleum in my laundry room, I'll get my own. This Wagner had the best reviews and was about middle of the price range, $22 bucks on Amazon (the range for heat gun prices was $15 to $30).
No matter where I wind up buying what I'm looking for, I usually check Amazon reviews first. Those people are brutally honest. (Plus, I learned something about fixing the xbox 360 Red Ring of Death in J. Hagen's review... awesome.)
