Glaze is probably the most misused word in detailing. In general they are ultra fine polishes that have oils in them that can fill in ultra fine imperfections, but they can detract from a sealant's ability to bond to the paint 100%. In short, we think this is the least essential step in the process and we generally skip it. However applying a glaze can really make your paint look amazing.
