SeaDek non-skid material

[JR-Shine]

Has anyone had any long-term experience with this material (SeaDek)? Specifically I want to know how well it wears over time. I have received some samples, and it looks promising. There are a lot of people in this area that swear by it.

Here is a link to the manufacturer: www.seadek.com

And here are some better pictures that I took of the samples:
