There's a lot of silliness in the finishing business, beginning with the myth that "flooding" will increase penetration. WRONG! no finish will penetrate more than a few wood cells deep, and as the first coat cures, it creates a barrier to further penetration by subsequent coats. What this means is that the first coat can/should be applied only enough to achieve full coverage, and wiped off after a few minutes. Following coats will simply integrate with it and build up the resulting film.
