Funny thing you brought back this thread I still have that same pan with the same baffle and same smeared gray RTV on the back seam... I was honestly expecting the RTV to start coming loose at some point but it's stuck on there just as well as the day I put it on back in 2011 or whatever. I wouldn't do it again but it's stuck on there so tight it would be a chore to remove lol
BTW I had that pan on a 360 that I put about 25k miles on so it was submerged in oil for a long time...
