I'm glad you love the Americana Wax! The applicators are for the Brilliant Glaze. If you already have a Red Hex Grip, then by all means us that as it is easier to apply with. Save the Microfiber Applicator pads for another product. I personally love to use them when applying VRT to my car trim. You can also use them to apply glass sealant, to level out quick sealant, and many other uses. They are very versatile.
I'm sure everyone has their own different uses for them as well.
