I used Thompsons on my deck too. Didn't last a month. I got 10 years on my treated deck, but replaced it with marine plywood a couple years ago. WIth the anti slip paint, it has lasted two seasons now. May need to touch it up next spring, but that isn't bad. Less than $20 bucks and a can of anti slip paint.
Hey D-Viper. Did you see that H&H has pulled their website? I sure hope they didn't close their doors.
H&H as a company has been disolved, and this one had nothing to do with the economy. H&H was profitable and had trailer orders backed up for several months in advance. One brother (H) had a major disagreement with the other brother (H), so H&H no longer exist. That is a shame because they had built the best quality trailers on the market.

I use linseed oil on all my exterior wood. It is not pretty, but I have a heavily used car carrier with a deck that is 15 years old and still solid. I clean it every fall before winter and re-oil it. Not slick once is soaks in.
D-viper. H&H has shut down all of it's operations. (Bankrupt). My snowmobile trailer deck was 3/4 plywood (Pressure treated). The first deck lasted 18 years. I still have two pieces of the original deck on the trailer. The only reason I replaced the deck was that my son had used my trailer to haul a couple engines on it, and "dropped" one as he was loading it. It almost went through the deck. So I had to replace it. It was getting soft from oil etc anyway. I admit, until I replaced it, I had not done any maintenence. After doing the work (not bad actually) to replace it, I didn't wait long before I had sealed the top, bottom and sides. I highly recommend putting something on it top and bottom. It is a couple hundred busk of well spent insurance against premature failure. Wood it a good deck material, but you have to do preventative maint on it. The time to do it is before you have trouble, not after it has already showed up. Unless of course you would rather be spending your dollars and time replacing decking when you could be out there doing something more enjoyable. It is one of those pay me now, or pay me later deals. Only the later you wait it usually costs a lot more in the end.
