The skiff is looking great!
There are many epoxy companies and many different types of epoxy. I use the West System. Other popular brands are: System 3, Maas, Raka, Glen-L, all can be found on the web. Not familiar with the home improvement store types of epoxy. The AeroMarine product looks to be just fine (the 'red' version).
If you order by mail, be sure to ask for the Hazard Material Fee added to the shipping cost.
