Sculpey Glaze is produced by the manufacturers of Sculpey and Premo clays, Polyform.
Some people complain that these glazes are too thick. If this is a problem, they can be thinned with water. Another complaint is that they peel. This can sometimes be remedied by cleaning the piece with rubbing alcohol before glazing it and by putting the piece back into the oven for a few minutes after glazing. The higher cost (per ounce) of specialty finishes (compared to Varathane and Future) is perhaps the trickiest problem. However, despite the troubles some have had with Sculpey Glazes, others like them. The thickness of the formula may offer a quick way to get a deeper shine than you'll have with a single coat of most finishes. Sculpey Glaze is available in gloss and satin (which is the "matte" version of the finish).
