Tried it on the board yesterday. You can definately feel that the board is slipperier, but in terms of a speed increase as claimed by the manufacturer I didn't have any of that. I wasn't going to go blasting by the boat
I tried a bottom turn out into the flats and didn't recognize any difference in how far out I could go. yet, the board seemed to release better - I could "sorta" pop it off the lip - which for me is AMAZING
I did 3, count 'em 3, 360's in a row and I don't do that. I don't know that I can attribute those to this stuff, but if it IS, then it worked great!
However, 3 seemed to be the limit, so maybe the stuff washes off? I tend to think I just got lucky on the 3's and it wasn't so much this product.
There is definately a noticeable feeling of the board being able to slide or release better - I was telling someone that it felt like I had lost 10 pounds. I think that's probably the best way to describe it. Of course, YMMV with stuff like this.
