No reason to get so defensive Steve; it's obvious that you intend to keep your truck. But anyone reading these forums would have to be pretty obtuse not to notice that many members do change trucks with fairly high frequency. I posted in order to bring the fact of the possible effect on value to any of those who may not have thought of it during their contemplation of this change.
Personally I like it and may well do it to one of my trucks pretty soon as a substitute for needed paint. It's a nice looking change, IMO, especially in dark colors. But I've also found that on my newest truck the 3m clear vinyl film such as is sold by Geno's and other vendors does an excellent job of reducing or eliminating rock chipping depending on the number and width of the layers applied. It's cheaper, invisible (nearly), and tough while being pretty easily removable without damage.
