Mix 3 oz. of unthickened epoxy and, using a small brush, coat the exposed edges of the inside laps to seal them and to keep them from absorbing excess resin.
There are two methods that we use to apply the thickened epoxy to the inside laps. Putting the epoxy mixture in an empty caulking gun tube is the quickest method, but the messiest. Using a disposable syringe is neater but slower, and requires the epoxy mix to be a little thinner, increasing the chance of drips.
