Just finished redecking our trailer. What is the best finish to protect the wood? The wood is a type of Fir, Hem Fir or Hemp Fir?
My dad thinks we should just spread used oil all over it, but I don't want to have to lay on the deck to tie something down with it all full of oil and the dirt that would be attracted to it. I'm sure I could just used boiled linseed oil, but I'm looking for some other options. Any suggestions?
I'd follow Pete's advice (Home Depot carries Sikkens), and if that doesn't work out, some kind of penetrating oil treatment would be my choice. I've seen some deck treatments that creates a varnish-like coating used on a trailer, and it turns into a flaky mess. Whatever you use, keep it up every year or two and the wood will last a lot longer.
