Hi! Could anyone help me out with my problem, I'd like to make a carbon bath, but the most nesessery thing about this project is good looks without anything accept carbon and good enough grip so that it won't end badly. If you have any suggestions leave them here please!

I have done a recent non skid on a carbon gangway for a yacht.

This non skid is a polyurethane resin sprayed with a non skid particle mixed in the resin. This particle becomes mostly clear and you can still see the twill weave through the non skid. This particle is https://international-yachtpaint.com/en/au/boat-paint-products/topcoat-finishes/intergrip .

You can also hand broadcast it onto paints, mix in paints or resins. Some people broadcast onto wet paint and then spray over this too to get a softer feel.
