There are companies here in the Bay Area, CA that sell a "life coat" system. It's ceramic based, or so they say and they also say it's "NASA" certified and used on the shuttle, bla, bla, bla...
These guys also say they are the "exclusive" applicators of the product and that it is a life coat. I looked up the product on line and anyone can buy the overpriced unknown material. Ceramic based?? Hmmm?? Lest try this on a ship lap wood house or a Victorian. I can almost guarantee it will fail.
Most of these novel "life coat" businesses come and go and also sub out to hacks in my experience.
Yes at around 6.00 a surface sq ft it's VERY expensive. I priced out a job that was bid by the life coat guys, shopped the materials and told the owner we could buy and charge extra for that material, but recommended they go S.W. A-100.
I got the job and the customer saved around 10 grand!
