Replaced clutch plates on my wife`s 2007 Boulevard while I had the clutch  side case off to install a Verslavy cam chain tensioner. I noticed the oil level window seal is coming loose. I`m thinking of putting some Blue PermaTex around the sight glass. I think I can get thin enough of a bead to help hold the thin gasket in enough to prevent leaks. Blue PermaTex or is there something else that would do better?
