Was his line-x with xtra? I have the front of my 04 cummins line-x'd white (grill, bumper, etc) and I have no problem cleaning it or keeping it clean. Maybe the xtra keeps stuff from sticking? Mine has been on that truck (which lives outside, here in the NM desert) for ~2 years with no chalking/fading etc. My dads jeep is orange, but with Xtra...and similar results. I actually find it easier to clean to be honest.A guy we raced with built a huge mud racing truck and Rhino lined the whole thing red.
1) The immediate drawback, besides weight, was that it became impossible to get really clean. Lots of little nooks and crannys in Rhino Lining where dust/mud hide out. It always looked dirty.
2) Mud can hang on to that rough surface in HUUUUGE chunks.
3) After two seasons of sun it had faded to a powdery whitish pink... and that was in Montana where we get waaaaay less direct sun than you guys do.
4) You should see how hard he worked to strip that stuff off the third season... WOW! Heat gun and spatula's for days.
On the plus side, dents were no big thing. Just pop them back out, and it hid the wrinkles well. I use Line-X on the under side of my fiberglass to help prevent the rock starring mentioned above.
I never thought about that! Very good point. I have a few small pieces I might do some expermenting on.the stuff is very flammable and you wont get it out with your everyday extinguisher ,i would never put any on a race car .it would be a long lasting paint job thats for sure ,the new trucks would fold in as thin as the body work is now lol.
