So I'm pulling my panelling off. Used a heat gun to soften the old adhesive and a 3M pinstripe wheel (pictured) did good work getting the rubberish adhesive that was left over. As for the "gunk" it left behind, it's just smearing it. It did take a little bit of paint, I think I was running it too fast, but maybe the heat contributed.

Am I doing this all wrong?

Turns out that when you have old trim like I do, moisture can build up in the cracks and hold in between the molding/adhesive channels and the paint. It weakens the coats over time. Couple that with the heat from the friction of the wheel and paint will peel. I can go get some goo gone from Autozone, but I hear good things about this stuff. Anyone ever use it?

Have had good luck with 3m's adhesive remover as well. But its not a quick job.
3M's wheel is great for the bulky doublesided tape removal, but the adhesive residue is just smearing. You're right though. Slow and steady

I used a heat gun and piece of fuel hose to scrape and ball up the adhesive. Like your fingernail but saved my hands from all the pushing. The hose was soft enough and didn’t take paint with it.

The tools made to turn those eraser wheels usually turn slower than a drill motor. Looks like the adhesive pulled off paint in places.

Pick your poison as far as adhesive removers, there are several decent ones out there and use a plastic razor blade or scraper. Give adhesive remover time to work and soften things up.

Looks like it been repainted around the moldings one time already so perfection is not going to happen.

3M Citrus-based adhesive remover. I work in adhesive coating and that's what works best for breaking down aggressive adhesive.

Correct.. gotta read the instructions on stuff like that. I believe 2500 or 2000 RPM MAX on the stripe-off wheel. I found that once it gets warm it doesn't work as well, so I would take a break and let the wheel cool off a bit then go at it again. I've never pulled paint with that wheel and it also never left any goo behind. Just rubber "dust" from the wheel that wiped off by hand.

*** Edit - been too many years since I used it, from the last reply saying 4K max I looked up the 3M wheel and it also says 4K RPM max. I do still maintain that once it gets hot it doesn't work as well, so spinning it fast isn't necessarily good. Also not recommended for lacquer paint.
