I have to disagree with the other reviewer. I was excited to get this and hoped it would solve the problem of some of the Julep colors staining, but after several test runs with and without the base coat...I finally have to admit, it causes problems.

No matter how light I put it on and how long I wait or how dry it seems, it makes the nail polish applied on top of it come out clumpy and usually unable to dry correctly.

Even though I love many Julep products, this one is a don't buy, IMO.
