Pau, if the outside is glassed with 6oz cloth you can could glass the interior with 6oz cloth up 1" past the chine fillet and leave it at that. What weight of tape do you have? The most common weight is 9oz which is very heavy stuff. Multiple layers of tape would be overkill and unnecessary given the thickness of the wood. Multiple layers of 9oz tape would be appropriate for bonding 1/4" or 3/8" ply in a small skiff. If you use tape you can put it gently onto the wet fillet then wetout with unthickened epoxy. The fillets don't need to be much thicker than the wood or wider than about 3/4" at the widest feathering. While theoretically the bonds are stronger with wet epoxy you could glass anytime after the fillets are cured, just make sure there isn't any amine blush or that you used an epoxy that isn't known for blush. If you are glassing the bottom panels and using tape then either glass first and tape later or tape first, let it cure, sand the rough selvaged edges then glass the cloth onto the tape. On my first s&g kayak I was unclear on strengths of materials and joints as they relate to the whole design so the thing simply had lots of wasted glass and epoxy.
