Old Rubber glue , removal?
You might need more than a hair dryer. A number of years ago my wife stripped all the old varnish from our boat's handrails and caprails, and she has done similar work on smaller pieces of the boat's trim, cabin sole sections, etc. A hair dryer doesn't generate anywhere near the necessary heat. She uses a Makita heat gun which even on low puts out far more heat than a hair dryer. It takes a heat setting of about halfway up the dial to get the proper heat for varnish removal, at least on this particular type of gun. So if the hair dryer doesn't have any effect on the rubber cement residue, you might want to try something that puts out more heat before giving up on the idea altogether.
