What is a hot coat?

Is a hot coat necessary?
A hot coat is always required. If not enough resin, than the fiberglass can easily de-laminate from the board. The Hotcoat more or less fills in the gaps left in the weave of the cloth after lamination. This not only gives you a smooth surface, but helps prevent water from seeping into the board over time.
Do you sand before hot coat?
Since you did a lot of the rough sanding on your hot-coat, you start sanding your gloss coat with higher grits. Most glossers start with 320 grit and remove the shiny surface first (don’t worry, it will come back). Make sure to keep your sandpaper as clean as possible, brushing the buildup off with a wire brush.
