This boat building is addicting! I took the day off today to work on it. I applied a second coat of epoxy to the cloth on the bottom with what started out as a brand new soft plastic spreader. Wow, that glass cloth is abrasive with just one coat on. By the time I was done with the bottom the spreader looked like it had been dragged behind a car for 50 miles.
Before applying epoxy to the sides, I decided to add a good amount of green tint (from RAKA) to my batch. I made three ounces for the 1st side and it was too much. It's 75 degrees here today, and this stuff certainly cures a lot faster than when it was 50 degrees in my basement this winter! By the time I was approaching the end of side one, the batch was a thick mess.
For side two, I mixed a smaller batch. I applied this with a soft plastic spreader. For those that follow, I can tell you that a spreader is fantastic for plain epoxy and allows you to get a nice thin coat evenly worked into the glass cloth. Unfortunately with the tint added it is quite difficult to get a smooth application. It tends to smear and that is not the best looking application. I think I will apply the next coat of tinted epoxy with a foam roller instead. I do expect to put a coat on the bottom mixed with graphite, and will likely apply that with the spreader. Take a look:

A couple of questions please:
1. At 70 degrees, how long do I have to wait to put on a coat of epoxy/graphite on the bottom?
2. What have any of you used to apply the tinted epoxy that has worked well?
