The only problem with Line Xbeing used that way is that the texture is not conducive to cleaning. That's why I had my Tahoe's bumpers and rocker panels done in a smoother texture.
And also, unless Line X has recently changed their formula, they have a problem with below freezing temperatures and cracking. If Line X gets very cold and takes a sudden impact it is very prone to cracking. I know guys that have had it in their pick up beds and had it crack under those conditions.
But your rig does look good though. Oddly familiar.
How often do you go to Hollister? Any desire to run the Rubicon?
