Different finishes may need different application methods.
Gasket lacquer must be used with the gasket system. The coating is so thick the excess finish must be wiped off with the gasket.
I haven't seen the Raptor video but undoubtably he's using something other than gasket lacquer if he isn't using a gasket. He may be using Bohning finishes, polyurethane, spar varnish, etc.
