It has been suggested to me that I use Boiled Linseed Oil as a treatment for Douglas Fir being used as framing on my 32' Friday Island Ferry.
The exterior will be sheathed in plywood and 6oz. glass cloth set in epoxy. The interior of the framing will be covered by 1/2' white cedar, tongue and groove. I intend to vent all of this.
My Question is what do people think of the linseed oil being used as a preservative on the interior framing as well as under the cabin sole.
I have read (on the internet for what that is worth) that linseed oil promotes mildew growth. Anybody hear that? Back in the day, when I was a house carpenter, we used to use a mixture of Turpentine and Linseed oil to treat the inside of Douglas Fir gutters
