Anyone ever use Hy-Tech#85 Barrier Coat

[bapos]

I am going to be getting ready to put windows in soon. I was thinking of spraying this on the inside of the bus before I either spray foam or use poly iso?

By the looks of it... it should sound dampen to some degree.... vapor barrier....and obviously radiant barrier?

The coverage rate is : 200 sq ft per gallon (for attic spray applications) So Im thinking maybe 2-3 gallons? I will probably be ordering the 5 gallon bucket just to be sure I have enough on hand?

Any other thoughts please feel free to put them here?

Many here have mixed the ceramic spheres into their exterior roof paint and report greatly reduced heat gain on sunny days so this product sounds like it would work also.
