Tenax Crystal Knife Grade Mastic

I have a roughly 2' x 5' piece of Granite (http://tanbrown.org) that is installed in a wooden frame.  The gaps between the wood and (http://maplered.com) the Stone (http://g603.net) vary from slightly less than the thickness of a dime to the that of a quarter.  I would like to fill this gap with a clear Material (http://g654.org) (truly clear like glass ... not clear as in Superior Water Clear Knife Grade polyester which I think looks more like "clear" silicon caulk).  The surface will have kitchen duty and (http://maplered.com) needs to be reasonably water and (http://maplered.com) stain resistant.

Will the Tenax Crystal product be a good choice for my application?  If not, what do you suggest?

Thanks.
