I discovered this some time ago (back before the price for alternator covers went out of sight). I started using EVERCOAT part #100116 to reduce the sound of transmission covers by coating the side close to the transmission with the stuff. Having bunches left over, I coated the back side of the alternator cover too. That was several years ago and haven't had to replace the one on my Interstate yet. It still looks new. The stuff has gotten more expensive since then, but there is probably enough material there to cover at least 12-14 alt. covers. If you have a friend, share. Works real easy by cutting to size, heating with a heat gun, then removing the cover from the sticky side and pressing into place. The heat makes it pliable enough to mold into the complex curves of the corners. Warning-too much heat and you could burn your fingers. After placing the material you can always add more heat and use a paper towel to press it down. Oh yes, it won't slide after it's put in place...Jim
I still have some of this stuff (Evercoat). Used it under my Kury trans covers on both Valks for sound deadening. Never thought of putting under the alt cover. Still have the original alt cover on my Std, looks new. Replaced the one on my I/S under warranty 12 years ago, still no bubbles. Sitting on 3 new alt covers I got from Europe @ $17 ea. Couldn't pass that up. (they are Not for sale)
