I'm set to install a new trunk seal on my 69 Spider. The last time I did this it failed miserably... mostly my own fault (lack of cleaning the gasket residue, etc). For those who have done this do you apply adhesive (I'm using 3M Super weatherstrip adhesive) to both sides inside the gasket? If so, how do you keep it from sticking to itself before install? Ok, so do you just glue one side? ANd also just one side on the metal lip? If so, which side does one do? Do I do it in short strips to make sure not to muck things up?
