I pulled the original trunk weatherstrip out the other day and found the bottom of the channel filled with petrified glue. What is the best method to remove?

My '67 coupe had loads of what I quess was 3-M 'Gorilla Snot' used to apply the seal.
I used my industrial heat-gun to soften it and then some 3-M trim adheasive remover liquid to scrub it out of the chanel.
Try an auto body supply store for the remover.

3-M makes a "release agent"....that is the product name...it can be purchased at almost any auto body/paint supply house. Places like Classic Camaro: Ricks: Paddock etc...carry it also.

Thanks I'll try it.

I just got the 3M stuff and tried it out. It changed the rock hard glue back into it's original gel form. I then used a squared-off popsicle stick to scrap it out of the channel. Thanks for the advice!!
