They are unlikely to have anything. Ditto Lowes. Try a marine or surfboard
place. Or maybe auto supply like NAPA.

Both require a catalyst to set. Epoxy sets up slowly once the catalyst is
added, takes up to a day to get reasonably hard. Polyester hardens much
more rapidly - minutes - and the set up time can be controlled a bit by
using more/less catalyst. The curing process generates heat, BTW, so use a
shallow container for mixing and don't put the container in the trash until
all is cured.
Also BTW, there are two types of polyester resin: laminating and finishing.
Use laminating when you plan to add additional coats as the surface remains
tacky after setting. The finishing has a small amount of wax added; the wax
keeps air from the surface so the resin sets hard.
