I got this bike for a great deal at a city auction but I'd like to change or just take off the decals because these were once police bikes. I thought I'd just go about it by soaking in adhesive remover but now that I've taken a closer look I'm not sure that's gonna work. The edge of the decal can be seen but can't be felt when you rub a finger over it. I think some kind of clear coat was applied after the decal was put on.

Anybody know something about this?
