Helmsman Spar Urethane not drying

I don’t quite understand it, since varnish will even dry on glass which is completely non-porous, but finishes don’t like to cure on cocobolo.

For me, wiping with acetone then as soon as it dried a coat of dewaxed shellac sealed the wood and allowed the other finish to cure. When you do the acetone wipe, you’ll actually see the oil (and some color) come off on the rag. When the cooor stops coming off, you’re ready to go as soon as the acetone dries. If you wait too long, oils will migrate back to the surface.

I’m curious why you chose spray spar varnish for a finish.
