meagain They got some brilliant people(scientists??) in CA., obviously.
I've used this stuff at work, on our uppermost concrete roof, which used to be a landing pad for 'copters. #1...it is blinding in the sun. #2...it is a waterbased product, meaning that if water gets under the surface, it will loosen/peel. Ya think traffic isn't gonna put holes in it, and cause it to loosen? Then again, how white is it gonna stay with that traffic?
Brilliant minds....just cannot be beat!
