Thanks for the suggestion, but I tried mineral spirits on the way to ethanol. It didn't work. My wife suggested hairspray, but she didn't have any for me to try.
I didn't have a problem with the first lens, but I guess I just got lucky and didn't have any marks in the middle of the lens that I needed to remove.
By-the-way, Home Depot has grease pencils. They call them China Markers. Not a very clean line, but they don't cause any damage and the marks are easy to remove. I may try the fine line tape if I ever have to do this again.
Thanks for the suggestions from everyone.
