A thin smear of wheel-bearing grease on both sides of a good paper gasket has always worked for me. I really really hate leaks, but I also hate it when parts are glued together or you have to scrape gaskets off.
This is what I do as well; only used RTV once and hated the clean-up when removing and reinstalling the unit. Grease and a Felpro gasket is cheap and easy.
