Armorpoxy deck coatings

Has anyone had any experience with any of the Armorpoxy products? I have a seven year old deck and the contractor bought deck boards in two batches. The first batch was nice fine grained wood that is performing perfect but the second batch (that was installed in the most high traffic area) is very grainy and has knots that are popping up along with end grain that sticks up. I want to make the deck more usable and not have the worry of bad splinters. I just want it to be safe to walk on my deck without shoes. The bad reviews on most of the coating products have convinced me not to use them but Armorpoxy looks more like industrial grade stuff. Any reviews or suggestions to my problem would be extremely helpful, Thanks.
