I used the Hippo liner as well, it worked well. Stuff i'm looking at now is called Raptor Guard. One of the autobody stores here had it, so i'm sure its available in Calgary. Its a rubberized bedliner like the Duplicolor stuff, but the rubber is stronger once dry and still flexible. Some auto body places have samples that you can check out to see if the product is what you are looking for. Just gotta ask.
