I bought this product to use between an enameled cast iron bathtub and vinyl flooring. The idea is good - the work will look cleaner since I'm a dirty stemmer. But this strip didn't stick to the tub at all (even after scrubbing, drying, and heating with a blow dryer) and while it had some traction, it wasn't as waterproof as I'd like for drops that splash outside. Bath. Let's get back to the old-fashioned (albeit sloppy) gagging for me.
