The price of Duratex looks pretty attractive in comparison to PolaneT + the catalyst, but how about coverage and wear? Any photos/comparisons of freshly sprayed boxes vs those that have been on the road for a few months?
I don't have any pics of the Duratex, but I'm actually surprised how well it has held up. I expected it to flake off, but it's handled minor abuse fairly well. The stuff I have it on is all B-Rig gear, so it doesn't really get trucked around a lot, but it is no better or worse than most comparable coatings.

It wears very well. I have some cabs that were done several years ago that still look good. Granted I don't haul my gear around as much as you guys probably do. It's also incredibly easy to touch up, just take a chip brush and stipple the spot. Scuffs will usually just clean off with window cleaner.
