I bought some of this stuff the day it came out. It works, but it makes the surface stiff and grimey feeling. I put it on the bottom of a deck chair cushion to see what it would do. It works exactly how they said it would, but it looks like crap.
Also, I have some net running shoes I put in on the back of. Again, it works fantastic, but it made my purple running shoes look like very fogged over.
They need to resolve the frosted color issue, but even then it drastically changes the feel of what it goes on. I haven't used it on anything else yet, but am planning on doing more this fall. I am building a backyard shed this fall and will treat the bottom 1' to 2' of all the studs and sill plates and probably the bottom edge of my siding to help prevent rot.
