Is there anything wrong with spreading it on evenly with your finger? As opposed to trying to lay down a uniform diameter bead like a robot does? I call that "buttering" on the RTV and it's way easier for me.
Whatever works for you. Want to be sure the FIPG material doesn't migrate beyond the gasket surfaces where it could get into the lubricant. Toyota calls for 1/8" bea, which doesn't seem like a lot but it works. My 04 Camry doesn't leak oil or even ooze oil.
It is critical to use a bead of the correct size and to apply it where specified. Joining the two surfaces together will squeeze out an even layer. Applying it with your finger may result in a low spot which will cause a leak.
I prefer a bead out of the nozzle. For some things, like the half-moon seals on Japanese engines or the valley seals on GM engines, I smear the end of the bead with my finger.
The less skin cells in the RTV, the better.
