Today I was fed up with looking at the Duramax and GMC emblems on the passenger door so I pulled them off . The drivers side were not on there when I bought the truck used probably dent/crash repair related . Anyway I now have black adhesive residue left over from when they were installed in 2001

I have peeled off and scraped with a wooden paint stick the majority of the thick stuff . Searched online and many suggest spray with WD40 or similar over a few days then hit with heat gun and the rest will come off .
Have any of you had success with this method ? Or any other tips ? I have a heat gun that I would only use on low setting . Today I hit the area with WD40 and will keep hitting it as weather permits as it's supposed to rain here for the next 4 - 5 days or more !

Many years ago I bought an eraser pad from NAPA that you chucked into a drill . It was beige in color and kind of like a giant pencil eraser . I used it to remove tape pin stripes and it did a great job . I think the friction created enough heat to somewhat melt the tape/adhesive . Any tips or suggestions are appreciated . I'm getting ready to get some graphics on the truck but have to get this area cleaned up first .
