Great stuff, very comfy on the knees. I got great results on my platform.
No problem to cut and stick. The straight lines are easy with a sharp knife and straight edge to cut along. Use a jar, can, saucepan etc. to get the radius for corners.
What are the dimensions for your boarding platform? Standard sheets of Gator Grip are 28" x 60" or 48"x 60". Talk to Chris at www.wakejunky.com/
he'll sort you out.
