    It depends on how thick the laminate will become. You can run into trouble with a thermolitic response (the goo heats up as it cures). It's difficult to tell by you photo, but it looks like you'll need to separate applications, to let the first batch exotherm, before the second batch goes on. It's still a same day operation, just a wait time between the first layers and the last. It all depends on how much resin is required to wetout the fabrics you'll apply. Ambient temperature, fabric types, hardener type and other factors all come to play in the time and amounts you can use and apply.

    Well so far so good, I got the epoxy bed laid in between the keel and sump after I tightened the keels nuts to spec and pumped out all the water in the void inside the keel I also took care of a couple other small spots on the rudder. Tomorrow I will layer up the sump and finish it with some fairing filler some sanding and a little paint and it should be good to go!

    Sounds good. Post some pictures of the process if you can.

    Well so far it's kinda slow going even with the fast cure hardener temperatures are really slowing the cure time and I have no way to heat the area!

    Go down to Wal-Mart and pick up an oil filled heater ($20 bucks). It's electric, no flame and it'll heat up the area nicely. duct tape a tarp around the keel and on the hull, letting it drape to the ground. Place 2x4's around the perimeter where it lays on the ground and put the heater inside. Turn the dial all the way up and you'll have cured goo in the morning.
