How to remove Plastic Restorer from the accidental application, Any bad affects for applying wax on top of Plastic Restorer

If you accidentally get some on other surfaces, you can simply wipe it off with a microfiber towel. If it's already dried, any quick detailer should do the trick.

There will be no harmful reactions to other products being put on top. I'm not familiar with Nu Finish, but we don't recommend using our Liquid Wax on top, simply because our Liquid Wax is not meant to be used on plastics.
