if i spray this on myself will i float?

Would you float?  Or would you sink straight to the bottom?  The physics of this stuff confuses me! 

Don't confuse the physics of surface tension with buoyancy.  I believe they found a way to practically minimize  the surface tension with water based liquids with this product.

is this product like RainX

Wet suit becomes dry suit?!?!?!? Gonna get this stuff asap to play with... Kayak sliding Friction-less/dry threw the water.... Yakasauras (KIWI angler) gliding threw the water like a T160...

Probably not. Under constant contact and at high pressure, the water will make its way into your wetsuit.

Confirmed that my local H.D. has the stuff; $19.99 kit
