marine ply finish

[coath]

hello
we have a skateboard ramp - half pipe with top made of marine ply
what would be the best finish to protect it. I was thinking of a decking oil
would this work?

it might make it a bit slippery. Given it is marine ply, do you need to finish with anything? Also, the wear and tear of the skateboards means that you will need to re-finish all the time.

it doesn't matter if it is slippery, it will get damaged but just wanted to preserve it as much as possible. would a decking oil etc soak into marine ply
