I use West System products exclusively when doing marine fiberglass repairs/modifications. There are many different filler options, so choose the one that best fits your needs. Mix the resin, add the filler and mix to your desired consistency, then apply. For me, usually similar to mayonnaise works best. Drying time will depend on your choice of hardener and if you've adjusted the resin/hardener ratio.
