That error is typical of colors such as that grey, or white, or yellow, or orange. They almost never come out stain free and usually are worse than that as happened with the Lambo. I think it’s a combination of both the lighter colors soak in the darker acetone, and they often don’t have the same quality of clear coat on them from the factory (idk why). Also, you can use a wood toothpick to get in the seams/lines of the car (while it’s still fully saturated).

I had no idea you could use dry erase markers for decal removals. Sick!

You a snack 😋
