Since I am not seeing moisture inside the car anywhere except the trunk I am going with a repair rather than a replacement.
I took out the aluminum trim. Finding a pucker on the inner seal a second layer, under the outside seal. I chose to use a liquid rubber product called three bond. It is the recommended product to put on crankcase halves on yamaha 2 strokes. It once it cures it stays very soft and is durable to fuel and solvents.
I pried up the layers and dried the inside with cotton swabs. Using a solvent to remove any oils.
Three Bond is easy to remove. if it doesnt work, nothing lost.
I used some silicone lubricant on the rubber when it came time to put the metal expander back in.
I have some Goop and was considering using it that is why I have the duct tape over the paint.
