I just came across this stuff via my dad, who heard about it from Xavier (NSX owner on here), who he works with...It claims to only need to be used once every 4 months....you put it on, then buff it off, then keep it out of the elements for 12 hours while it forms a protective "shell" around your car....I haven't been able to test the results yet, as my car is still in the garage for that 12 hour period....i do know it goes on very nicely and buffs off almost efortlessly....it also gave my paint a deep shine....so far, i'm impressed...anyone else ever used this or heard of it? oh, it's liquid, btw...
