My neighbor and I share a property line that is a wood fence, we replaced the slats like 10 years ago. Every 3 or 4 years I paint the slats with boiled linseed oil, just to give it some rain resistance and extra life.
Recoated it yesterday, he bought the materials so we could spray it on. Two gallons of BLO and a gallon of odorless paint thinner came to $107. Which we split. We did have about a third of the spirits left, which I took as parts cleaner. But geez!
Toward the end of the job we ran low on BLO, but I had 1/2 gallon stashed away that I had picked up at a garage sale. That allowed us to finish. Man, I's so glad I grab partial containers of chemicals at yard sales and such!
