I am not familiar with epoxy USA. That doesn't mean its not as good, I just liked US Composites pricing. I want to say it is around $340 with shipping to NC for a 7.5 gal kit. It comes in 1 gallon containers. You'll want to start with at least 7 gallons so if their prices at that quantity match up then I would go for it. You'll also want the slowest cure available. I was fortunate that most of my big layups took place when it was 40 degrees outside so that gave me the time to work for several hours on a single batch. Now that it has warmed up I am having to mix smaller batches and it is more challenging.

I like the 45/45 and was advised that is the way to go from the fellas on boat design.net.

Here is another tip that I have learned, MEK costs more than acetone per gallon but you save overall because it does not evaporate nearly as quickly but still quickly
