I am on my second bottle of this product and like it. I have used the regular REACT base coat for years (great product). I'm not sure if one coat would hide ridges. I use one coat of this base, 2 coats of Morgan Taylor color polish and one coat REACT top coat. The results are very smooth and last approx. 7-10 days before starting to chip. I have been using Morgan Taylor products exclusively for several years and have seen improvement in the health and look of my nails.
