Epoxy Filler

First sand the repair with 80 grit sandpaper to roughen the epoxy patch and allow the next layer to adhere.

Now use the same 105/206 epoxy with the 404 filler. After mixing the epoxy, add filler until it is a peanut butter consistency. This is required to keep the filler on a vertical surface.

Spread the filler to cover any irregularities and to hide the fiberglass weave.
