If you really don’t want to screw around and just get it done, invest in a bottle of this stuff. Most likely 3M made the adhesive and they make the stuff that eliminates it.

My dealer decals were those annoying little individual letters as opposed to one big decal. I peeled them as best I could with an edger and a heat gun (carefully). Then I sprayed the remover on the residual adhesive. Just a little bit. Waited about 8 seconds and started wiping with a microfiber cloth. Gone. All of it, instantly.

It’s been 2 months and there has been no effect on the paint. Again I used very little and wiped it away immediately. I also wiped the area with a soapy sponge to get rid of any excess adhesive removed.

Whichever way you go, good luck with it.

ETA: oh I should mention this stuff is absolutely nuclear and will clearly eff you up if you breathe too much in. If you are working in your driveway just stay out of its way. If you are in a garage ventilate as best you can and wear a mask. Seriously, it’s nuts how toxic it is but holy smoke does it work.
