RM, You might want to study this a bit. It has a lot of good info on how to fabricate and install your Stringers, Deck and transom...
Fabricating Decks, Stringers, and Transoms
Since you're in Indiana, your best cheapest source of online resin will be here...
Resin Supplier
This list will be a Good start for how much "Stuff" you'll need to do the Deck, stringers and Transom on a boat your size. It's not EXACT but it'll be pretty close.
15 -20 Gallons 435 Polyester Resin
10 qts Cabosil
1 lbs 1/4" chopped strand fibers
25 yds 1.5 oz CSM
15 yds 1708 Biaxial Cloth
2 dozen 1 qt plastic mixing buckets and stir sticks
1 - 1/2" x 5" Fiberglass "Bubble" roller
2 dozen Short nap 6" nylon roller covers and trays
2 dozen 3" Chip Brushes (cut ½ the length of the bristles off)
This is approx. $750 worth of materials and then there will be shipping on top of that.
If you buy resin locally by the gallon it WILL have wax in it and that's really not a good thing. You will have to sand and wash it down with acetone if you want to put another layer on ( and you will) and it's never as good a bond as if it didn't have wax. It's also almost double the price.
