I had Rhinoline done to my '84 CJ7 a couple years back. Then This summer I had Line-X done to my '79 CJ7. The products are quite different. Line-X is a harder material, with a finer textured pattern than Rhino. It doesn't stretch or give much & I suspect it adds a little more structural strength. In my two installs, the Line-X material sticks tighter - harder to peel off if you need to than Rhino. In my '79 Jeep I built a big sub-woofer and had the exterior covered with Line-x to match the rest of interior. Line-x can mix the material in colors to match your jeep color scheme...not sure if Rhino-line does that. Line-X is beginning to get a good business spraying the exterior of jeeps. iI think I like Line-X the best, though Rhino is easier on your skin when you're crawling around on it inside while working under dash, etc. I think both are good products. I have no experience with Durabak & other s you self-apply. You can take small items off your jeep to Line-x & they can spray them with precision...I took off my tube rocker sliders and had them spray them to match the interior. My local Line-x dealer has an empty Pepsi can on display - they coated the exterior & the interior ver neatly...pretty impressive...I don't think Rhino-Line applicators spray with that precision ...at least they didn't on my Jeep. Rhinloiner is rubberry, stretchy and has a coarser pattern on the surface which some people prefer. That's all I know.
