A couple of weeks ago while in Death Valley, I drove on a little trail that was completely overgrown on both sides by 4' - 5' sagebrush & other trees and nasty bushes. I could hear the high pitched scraping noise for about 1/2 a mile or so there, and then when I returned. Anyway, I scraped the crap out of both sides of the Pathfinder, from the front bumper to the rear. After researching a bit, I bought some of this stuff:
It seems to have worked fairly well, although I'll still need to work on a couple of the larger scratches as soon as my touch up paint arrives. Then I'll have to fix some big dings in my hood & wax the beast. If it survives the crazy wax I use, it should last quite a while.
