Sorry Ross, the old instructions used to be do one coat, leave 10 mins and then repeat twice. So it's a total of 3 coats in half an hour. Then leave for a few days. So I like to think of it as a session = 3 coats over 30 mins. Don't go too thick in each coat to avoid runs. You'll get the hang of it. There are a few in depth posts about the Cabot's schedule if you have a search around here.
