I have built many stitch and glue boats. &nbsp;For all of those boats, I've thickened my epoxy for fillets with a 2:1 mix of cello-fill (or fumed silica) and wood flour. &nbsp;The instructions for this Annapolis Wherry tell me to just use wood flour. &nbsp;I tried this, and it looks awful-- like cellulite! &nbsp;I'm about to mix up a batch of the other, and smear it over the top. &nbsp;Am I doing something wrong? &nbsp;Why does it look like this?
