True but I guess only if done at the time the paint was applied and not after giving it time to cure. If it’s been some time, I think wet sanding is the solution.
The good thing about Dr. Colorchip is that the blending solution is also a solvent. It allows you to remove the paint and start over again. You can remove part of the paint or the whole thing. It depends on how much you work it.
If it's sat for a while and hasn't had sealact applied to it, it will definitely require more effort to remove than if it was done just after applying the paint.
