epoxy help, so many options what one to use

I am getting ready to start my new project. It will be a small kayak like boat. It will be hand laid with a male mold using a roller and squeegee.

It will be 2 layers of s-2 8hs 8.9oz then 1/2" divinycell ribs and transome with a layer of glass over those. Then a single or double layer on the inside. The bottom will then be rolled with a layer of resin with a graphite filler.

I am wanting to use a faster setting low viscosity as clarity is not a issue as it will be painted with a oil based paint.

It seems there are a ton of options out there and pricing really varies. I have not called around as I’m sure they will push me towards their product and not what is best for all that is out there. I’m guessing I will need in the 5gal. Range for the project.

I use the Adtech with slow hardener, super clear with a very low viscosity.
highly recommend.
