Rhino Liner or other types of paint-on liners

Having had a great deal of experience with ATV trailers and loading/unloading them, you don't want a smooth deck. Smooth = slippery. Makes it much harder to load safely, especially when your ATV tires are wet or muddy. Also you can slip and fall when mounting/dismounting the ATV. Rhino liner is generally smooth, I know its slippery when wet in the bed of a pickup. Line-X is rougher and a superior product as far as texture goes.

I'm wondering about the flexibility of those type of products on a wood surface that will probably flex. I'd try the canned product from Menards or similar stores, and make sure its the textured version. Proper prep is probably the key.
