I built a shed and oiled the exposed wood with old engine oil from the car and bike.
Then did an oil change on the boat and had some real black oil. So, I gave it another coat of the real thing (yanmar oil)
Still got some left over and looking for something to coat!

Nice build but wonder what the vapours are going to be like when the heat of summer comes along. Don't worry you'll already have you COVID19 face mask
