I don't know of anything that would produce noticeable texture, that would stand up to flexing, temp changes, and humidity changes that a coach sees.

Have you tried filling a divot and leaving the filler "proud"? i.e. sticking slightly above the surface. After it dries completely, sand it down flush.

I notice on drywall that the filler always shrinks, so if I use a putty knife to fill it in, and scrape flush, then it will be slightly recessed when it dries.
