Clear Gloss Topcoat is a crystal-clear acrylic waterbase lacquer that has 100% burn-in between coats, without a time limit. That makes it repairable, much like nitrocellulose lacquer. It is a thermoplastic resin and will shrink and move around with the heat of buffing. 25-30% of the final finish thickness should be lacquer topcoats. It sands and buffs well to a high gloss, with good hardness and durability. Full chemical cure occurs in 150 hours.
Waterbase Retarder or WATER can be added to reduce viscosity. When hot/dry conditions cause the finish to dry too fast, thin with 5%-15% Waterbase Retarder.

also didn't say anything about NEEDING any other product for curing either on the company website or the label.
Some time ago I researched this and the StewMac stuff is made by Target Coatings. Here is a link to their web page.
