Greetings-I'm about to build an Annapolis wherry for a friend's sister; she's gotten as far as stitching the hull together. This is a paying gig, and I need to know how long it should take to finish it from this point, minus epoxy curing time, so I can accurately decide what to charge. Also, I have some leftover System Three w/medium hardener left over from my Pygmy; I figure I can save some curing time if I can use this for gluing and filleting. Is it compatible with MAS? Thanks, Greg Root
