im actually using teflon tape on my Accuras plug. I dont see any difference between it and the grease. Neither allow any blowby. Both come out easy. The grease i use washes off with water. Im also using pyrodex RS.

BH209 is to hard to find around here. Goex is a hell of a lot easier to find LOL. but still a 2 hour drive, so i stick with pyrodex.
