I recently bought a Redline leather cover for the sliding top on a center arm rest. In the Redline "How To Install", it is suggested that 1/4" staples are used. Well, I tried that and most of the staples bend without going into the plastic. I am about to resort to super glue (have about 6 staples in). Any ideas on a better type of staple to use, or go with the glue? Pics show staples, and stapler.
