Best way to remove black 3M glue - front trunk Options

[RickS]

The previous leaky front trunk seal was glued in with a generous amount of black 3M weather strip which came in a squeeze tube. After 3 hours of getting way too high on Goof-Off and getting about 1/4 of it off, I am turning to the brain trust for an easier method that does not involve repainting the channel.

Thought about using a heat gun, but don't want to blister the paint. Ideas?

Was at the specialty auto body/paint supply store and quizzed them about the 3M adhesive remover products. Their thought was that any 3M product which won't damage the paint is essentially like Goof-off and has about the same strength.

Sooooooooooooooooo, what I am doing is soaking the adhesive with Goof-off and letting it sit for a couple of hours. Then using a screw driver which I rounded off the corners and blunted the blade to slowly scrape off the gunk without damaging the paint. It's slow but the vapors are gone by the time I start scraping.

One thing I found in the process was a surprising amount of surface rust in the channel between the headlights. Dam those low points!! After getting the worst of it out, I am treating the remained with Rust Mort and then painting.
