Sorry to sound stupid but what part of your binding do you glue? I'd never heard of it until an earlier post today.
I use it to get the diagonal seams in my strips, then to glue the binding to the back after stitching to the front. Then I either hand stitch or machine stitch and when done, the glue washes out. It makes for a nice finished look. I also use it when trying to match patterns on a border. For that, I press under the seam allowance, match it up, glue baste, sew on the crease and it's perfect! Sharon Schamber has some great video tutorials - see link below.
