Have heard folks talk about acetone.
I would think acetone would start getting to any clear-coat and dull the finish. No?:Shrug:
Welcome to the Gang from Western Colorado.
You might try Easy Off Oven Cleaner, spray on a micro fiber rag and rub ... it has worked for me before ... just be careful and test it in an inconspicuous spot first, not all clear coats are alike.
I once watched a pinstriper called "Jake" remove a bad striping job on a '34 Ford Streetrod with Easy Off oven cleaner before re-striping the car. Didn't appear to leave a "ghost" image.
As Fuzzy said, proceed with caution!
