I've been repairing rods for years and have found that a #1 Xacto Knife to be the best tool for my work. It allows me to work safely with it rather than an iffy razor blade. Start by cutting the thread along the top of the old guide foot to remove the old guide and then you can peel the old thread off. You will likely find that you can grab a thread tag end and unravel the winding from the blank. Once the thread has been removed, use the Xacto knife to gently scape the old epoxy from the blank. Care is needed not to cut into the blank. Clean the area with rubbing alcohol. Scraping the old epoxy will prep the blank for the new guide thus allowing a very nice and smooth new thread wrap. When properly done and finished with epoxy, you should end up with a beautiful repair. Hope this helps!
