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.
