Guys,
We went with
Sanitred non-slip and it's serious stuff. It's the same thing you find on concrete industrial floors. It's all rubber, can cover a multitude of sins and is really non-slip. It's a more agressive surface than Interlux, but it's a fishing boat. The white looks great and UV tough. 10 year guarantee. We'll see how it goes.
You can order a sample kit to try it out.
