I think it looks good. I agree that it wont stay that way and the up-keep to try and keep it looking that way would not be worth it to me. If your going to wheel it then great, that is some awsome protection for it.
I did that to my old TJ and loved it. Never gave a crap about sticks and branches scraping down the side of my Jeep. Got a soft nylon scrub brush to scrub it down when it was muddy. I was actually considering this as an option to paint when I trade for half doors. I like the black door look on silver. I also already have this stuff on my grill and pinch weld, so thought it might look good. Still undecided.
No doubt that that stuff is very durable but my concern would be about how would you touch up scrapes and such that has pealed all the way to the original paint. Iím thinking that rubbing against some rocks would be enough to do that kind of damage. I have no experience with the stuff so perhaps Iím off base with my concern of durability, not sure.
I have a 1992 Wrangler covered inside and outside with Line-X Exterior. The guy I purchased it from did it himself and did an awesome job. I really like it and I think it looks pretty sweet too. It was done a few years ago and still looks brand new. I rinse the dirt off with the hose and then cover it with tire foam.
