Sorry it took me so long to see this! Not sure why you are having trouble wiping it off, I have not had this issue myself. A few things come to mind though. 1)- Maybe you are working it a bit to long and it's drying out on you. Try less passes and see what happens. 2)- Maybe you are using a bit too much polish, a little bit of S3 goes a long way. 3)- Possibly 1 and 2 both. If you are still having an issue wiping it off, a spritz of Eraser prior to wiping it off will help.
