Yeah sorry I didnt read the linked instructions. I'm not doing that either lol. 6 coats the way I described will seal and protect a wood shaft to the point it is about impervious to everything except breaking it.In the link I posted the epoxy coating instructions have layers of polyacrylic between layers of epoxy. They do 13 coats total with 12 separate steps. I bet it would take a full week minimum just for the coating.
Your method sounds way more reasonable.
