SUPERTHERM multiceramics coating - anyone ever used it?

[WHIZBANG]

SUPERTHERM multiceramics coating [http://www.supertherm.net/home.htm]
makes astounding claims:

"SUPER THERM equals an insulation value of R-10 (refers only to inside wall conduction ability because the extent of the coatings' radiant ability is not fully used.) The R-10 equivalency is a minimum in keeping heat or cold inside a room) or equal to 6 - 8 inches of batt insulation on controlling conduction. Its heat reflective ability on a metal surface facing the sun will provide an equivalent range of RI9-R28. SUPER THERM outperformed one inch of Styrofoam board, one inch of polyurethane foam, and all other reflective coatings in an insulation test on metal roofing conducted at the University of California at Davis. It outperformed 4 inches of polyfoam equal to R28 in Japan. "
"SUPER THERM controls cold and heat from traveling through it providing a controlled zone that avoids conditions conducive to condensation."
"The coating will last a minimum of 25 years, and we expect 30-40 years."

It seems to me if half of this were true, every steel boat on earth would be painted with this stuff!!!!
They claim its been used around the world for years but us wacky Americans are resistive to change.

Does anyone know anyone who tried this stuff?????
