Great Product
Rock Hard Top Coat does what it claims to do: it hardens and preserves your nail polish. I have never been able to keep polish on the tips of my nails for more than a couple of days. With Rock Hard, it lasts a week or more despite doing dishes and assembling furniture. It does not create unsightly bubbles either, as long as you let your coats of polish dry for a few minutes before applying the topcoat.
