Herzog said:I bolted mine on, but if I were to do it again with Roll Plastic, I'd Zip tie it. The plastic expands in the sun and gets very wavy. I'd imagine that the zip ties would give it a little more give and look better in that situation.
The zip ties don't look bad at all. In fact, I didn't even notice many of the skins had zip ties out there. It's all about how closely you look at it.
With zip ties the plastic still gets wavy with temperature changes.
My biggest peeve with zip ties is that it's extremely easy to rip the body panel off on obstacles. (breaking the zip ties) I always ended up with half-dragging panels that I'd have to take off the rest of the way. That's why I bolted them on this go-round.
The biggest thing that helps keep panels intact though, is to have the "nerf bar" stick out a little bit from the side. Mine sticks out probably one tube width (1.5") and I don't destroy NEARLY as many panels as I used to.
