I'm getting ready to place an order with Raka for my epoxy and fiberglass for my OneOceanKayak's Storm. I'm going to build a carbon coaming according to Vaclav's instructions. A few questions...

Which fillers do I need (and how much) to putty the inside stems, butt plates, and attach the coaming ring?

How much of the 5oz carbon twill cloth is needed to cut bias strips for one carbon coaming?

Anything else I should pick up while I'm at it?

Thanks and Happy Thanksgiving,
Greg
