Are we talking about the same stuff?
Also it shows a primer and a finish coating which seem rather expensive for application on cloth which has a limited lifespan.

: Hello,

: I'm in the proces of making my first SOF kayak, after a couple of

: I've read Coelan is the top product to use, but it's quite

: oil based varnish and topping it of with a coat of Coelan silk.

: I've posted this question on the Greenland forums but no responses
: yet and i thought i'd try here as well. I've asked Tony Nuskin
: at premapro the same question (but put it a little) but haven't
: had an answer yet.

: Would it be a good idea or should i go full Coelan to get Coelan's
