Line-X for roof

Line-X will flex quite well. I don't see where this should be any kind of an issue.

Most all bed liners flex, as the underlining bed expands when it gets hot, and flexes as you drive down the road.

we have had a fifth with an aluminum roof. 1990 Year. have never done anything to it except calking in a few places. why oh why did they ever go away from aluminum?

Someone even did the whole vehicle,,van in this case

Why not?
Those "specialized products" are many times just relabeled to hit a certain market at an increased price. If the product performs to fulfill a certain need, then use it.

This type of product has been advertised and used for several years now.
Many of the shops have the ability to spray the roofs in several colors.

The video I watched on youtube a few years back showed a company out of California spraying it on. It is different than the bedliner stuff. It was silver and had a huge amount of UV protectant in it. It was by no means cheap but then again replacing these rubber roofs aren't either. If/when I have to do my roof I will seriously be looking into it. I think the little bit of added weight would be worth the piece of mind that the roof has a worry free lifetime warranty.

Only one reason.....$$$$$$$$

For now, considering the cost, I am putting eternabond tape on all seams and joints I think will leak. Thanks for all of the comments on this subject.
