SeaDeck.

Alex from GA

Went fishing with a buddy and he had Sea Deck on the bottom of his Flint kayak.  It was die cut and really looked good and offered more solid footing while standing.  Anyone else seen or tried this?

Sea Deck and Oceangrip are pretty good with numerous colors and grip designs available. Both give you a somewhat cushy nonskid surface to stand on. There's a few others out there. Google deck grip or kayak deck grip.

I have a couple SeaDeck pad's, cut to size with the neat die-cut borders in my canoe mainly to cut down noise when I'm jostling around pliers, paddles, anchor and stuff... DIY installation and its been down a few years of hard use with plenty of exposed sunshine, grime, and mud.. good  stuff.
You can order pre-cut kits for some kayaks, or get a template kit and design your own, as well as purchase bulk material and try to cut it your self but the cut it yourself does not give you professional die-cut relieved edges. They will also custom engrave your own personal logo or name into it.

Just got a color sample kit from them trying to decide on a color and style, pattern cut or brushed,  for my current kayak, The kayak is used and who ever had it before me put some off-brand eva type padding in that is stuck down pretty good but is peeling at a corner and an edge as well as has a tear in one spot, want to replace this.

Have more than one friend that has SeaDeck padding in their boats and love the stuff.
