Looks like a deal, but is this site safe or scamer?

I did a similar product (Herculiner) on my truck bed a few years back. It didn't work so well. It was a pretty thin coating when it was all done and it wore off quickly (within a few months) in spots. It faded quickly also. I wouldn't do it again. I've since had the Line-x and it was much better. That was well worth the extra money. I would guess the Rhinoliner is just as good as the Line-x.
