Arlene,
The first coat is 1/3 oil based exterior primer 2/3 linseed oil 1/10
mineral spirits (to help make it penetrate the canvas fibers). The
second coat 1/3 linseed oil 2/3 exterior primer.
That should fill
the canvas, so all is left is to sand lightly and apply three coats
of spar varnished thinned with 1/10 linseed oil.
Sand the first
coat of spar with wet sand paper 180 grit; the second coat with
wet 320 grit.
The result is a very flexible hull that looks like a mirror.
I spent $50 on the the paint + linseed oil + mineral spirits
(only a quart of the latter) and $17 on a can of Captains spar varnish.
The deck does not required more than a coat of varnish, so just
concentrate on the hull.
I learned this method from Bob Boucher's video. The previous skin
of my kayak had aircraft dope, and that will not happen again.
I hope this helps, cheers
- Julio
