This may not be an implement to some but it is vital our operation. I built a 16’ trailer in high school, just cuz I didn’t want to always borrow the neighbors trailer all the time. It was a good idea since we hauled hay out of the field with it all the time & in the winter, I would sell cedar logs to a mill not far away. Back then, the deck of the trailer was red oak. While not a desirable piece of timber, I didn’t want to pay a treated lumber price at the time, nor do I want to now. The trailer has been restored & again I have a red oak to deck it with. Question is what can I put on the wood to get it to last for years to come?
