After a little digging at Autopia, I am seeing indications that even under a sealant, a glaze only lasts a month at most, and in best case, it just fades away itself, in worst case, it may take the sealant (a 4-6 month product) with it, along with any and all layers of wax over that. An unprotected glaze can only make a week, which is far shorter than even a wax. Ergo, I'll drop the glaze, and that puts me back just under $200.
