MK Advanced Stone Sealer Quart .946 L

I bought this for the 12"x12" polished marble tiles on my bathroom floor. I wanted something to protect the tile from stains (make-up powder mostly) and small scratches.After trying this product on a leftover sample of tile, it left a very obvious residue on the polished surface. Customer support suggested I polish it until the residue is gone, however, now I think in doing so the stain/scratch protection was also polished away.I applied the product to the floor in my bathroom and literally spent hours polishing off the residue and the tile only covered a 5'x4' area. The product was applied about 6 months ago and I already have a stain from a small drip of blue hair gel (also found that good hair products are rarely clear in color). I now put my makeup on in my bedroom to avoid dropping a blush compact on the floor.
