Step 16 Apply second coat of epoxy on the outside

Once the first coat of epoxy on the outside has cured, you can apply a second coat.

Use the same procedure to apply the 2nd coat as the first coat. Be sure to spread the epoxy nice and thin, so that the epoxy doesn't run. Since the first coat of epoxy soaked into the leather and sealed it, the leather won't absorb the 2nd coat, so you won't need to go back and keep applying epoxy as it soaks it up, like you did with the first coat. You won't need to use much epoxy, just mix up about 1oz (.5 oz of each component). You probably won't use all of it.


(Optional) You can add some fumed silica to the epoxy to thicken it. This allows to you spread it thinner and prevents the epoxy from running, and from "bunching up" - Like when you try to spread water thinly on a piece of glass - it won't form a uniform film, but it will separate and bunch up. The epoxy will sometimes do this to a small extent if you apply it too thinly without a thickener.

You should thoroughly mix the epoxy first, and then add some fumed silica to the mixed epoxy. Add small amounts at a time, to make mixing easier. Keep adding fumed silica until you get something like a "snot-like" consistency. Note that the fumed silica will make the epoxy a translucent white color. Don't worry, when you spread it thin enough it will still be quite clear.
