I have heard of using those rubber bands. I expect that is a very good way to go. I do like the Duco cement because I can place the guide on the rod, and once the glue hardens that guide will not easily shift it's position, and If I do want to move the guide it will come off with a light tug, and the old glue scrapes off of both the rod and the guide with no difficulty. I guess it's a question of whatever turns you on. I think I will give the rubber bands a try just to see which I like better.
All the best,
