Wow. That stuff sure does look pretty neat, but for that price, I had BETTER be able to cover at least one entire suit with it.
Also, seeing that made me think of the stuff they sell for cars. Can't remember the price per can, but it was used to spray a protection layer for the bed of a truck. At least that is what I am familiar with it being used for. How would that fare up to being sprayed on the EVA foam?
Looks like we really need to see this flex seal stuff tested. Find out if it's sandable and if it is, how easy it is to sand and then of course do some stress tests with it, but judging from the video, bending it seems to be okay. Although, we would have to see how it reacts when bending after applied to the foam. I wonder if the stuff can be found at any store though? I've seen plenty of "As advertised on TV" items being sold in some stores.
EDIT: I just looked into the reviews and that about this stuff and from what I am gathering from nearly ALL the reviews..............DO NOT BUY THIS STUFF!!!! Apparently they charge $20 or more for the shippin gon the 2 cans. You are MUCH better off going to a hardware store or auto store and getting something similar since liquid rubber stuff has been around for some time so this flex seal isn't something new and revolutionary!
