hmm, i dunno about that water based system. I mean, its REALLY nice that there is no fumes, but in general a $30 respirator would take care of any would be fumes. Anyways, from anyyone that i've ever talked to or have read, water based products are just not as strong as oil based, urethane or paint.. Also, the 3 day cure thing kinda boggles me?? So unless he has found something "new" i'm curious? However, it looks like urethane coating. Anyways, it still comes down to two things, line-x and such use a polyurea based product, which is stronger and has better UV resistance as well has an activator that is added, most DIY kits are polyurethane based and don't have an activator. I'm guessing the Second Skin kit was one part?? I have used a MYRIAD of bedliners and the best i have found are made by Dominion Sure Seal, they are gator gaurd which is the only epoxy based kit i have found, and it does very well when applied to bare metal, as long as enough coats are applied, and then hippo liner which is a two part system, (ie. it has an activator) and they also make a water based system as well. HOWEVER, prep, prep and prep, and then coats, 3 coats is minimum being brushed or rolled on, anything less won't be strong enough. I've coated rocker panels, the floor of my previous vehicle, as well as the bed i made for it, the rear of the cab, inner fenders, frame rails, and other various body work, and pretty much everything was done with a different product....
