    I'm at the stage where I'm ready to start finishing the interior of my OT Charles River. What is the consensus for wood preparation prior to the of applying the multiple coat spar varnish? I've read some people use linseed oil or linseed oil blended with this and that while others simply use thinned varnish. Regarding thinned varnish, has anyone had experience using Danish oil?

    Danish oil aka Watco, aka, Fornby’s is basically a mixture of oil and varnish probably with some thinner and Japan dryer thrown in. It is primarily used as a furniture finish. I personally prefer an initial coat of orange shellac. Almost any finish, especially varnish, bonds to the shellac. The shellac gives a very nice warm color to the ribs and planking. Not sure what the advantage of an initial coat of Watco would be.

    Years ago I worked on a canoe for a customer who subsequently finished the interior with Deks Olje. Looked great, but I don't know how it held up in the long run.

    It is hard to go wrong with the simple schedule of sanding the interior to 220g, first coat of good, traditional spar varnish thinned 50%, second coat thinned 75% and the remaining coats thinned 90%. Use the manufacturers recommended thinner.
