I have been doing mayo for a while as well. I started as my rib slather in place of mustard, and gave it a shot last year on my Thanksgiving bird after a wet brine. Came out good. Mayo is just oil and egg whites, so other than the jarred consistency, it's not that shocking that it works well. If you were to have someone oil their bird, then brush with egg whites (like a pie crust), no one would bat and eye. Mayo just skips a few steps and does it all at once.
