Then immediately sprinkle a generous coating of rubber grit to the surface.

you can also use coarse crushed pecan shells (or similar)...think media for sand blasting but not sand.

Sprinkle it on the wet paint...let that dry...put another coat of paint on top.

The benefit over rubber/sand additive is you can always sand it down if you need to.
