I used to buy it from the Mobile oil bulk distributor and added 1 gallon of mineral spirits to five gallons of shingle oil (back when mineral spirits was cheap) and used a weed sprayer to apply it to my cedar siding every 5-6 yrs. At the time it was way cheaper than linseed oil. The down side to it was, that over time it attracted dirt and turned almost black. It does come back to it's original color after pressure washing. I switched over to Duckback penetrating sealer about 15 yrs ago, and it does a much better job without discoloration. Not cheap at $130 for 5 gal. But I buy a few buckets every year with 20% off coupons, and clean and reseal every 6-7 yrs. the siding still looks great after 35 yrs. For the trailer bed I would go with the used motor oil and diesel, and try to park it out of direct sunlight. Mike
