best way to protect wood?

[metallitera]

my new to me trailer has a home made rear ramp door. they made a metal frame and put 2 like 3"x6" sheets of plywood, i think its marine grade. looks to have a plastic venier on it. anyhow, one side is rotting out and i wanna replace and have it stay a while.

what should i treat it with? i looked at thompsons water seal, polyeurathane coatings, and that epoxy garage floor paint. what would work best?

If I were you I might consider spraying the new lumber with Herculiner! That would be very durable and would last quite a long time. I actually have an ATV trailer that is all wood on the flooring and am thinking about doing this with those planks so they remain protected for a long period of time. Not to mention that it would add extra traction on that ramp for whatever you might load up onto the trailer.

poly coatings works great too

I stained my trailer deck with Cabot natural sealer. Its the same stuff that you would use on your deck. I think its like $30.00 a gallon but it has stood up to the abuse and weather. I gave it two thick coats and the wood still looks brand new 2 years later.

I was tought by an oldtimer to treat my tailers with linsead oil and thiner. 50/50 mix. Cheapest you can find. Do it on a hot day works best. I use a bug sprayer to apply or you can use a paint roller. With a 2 gallon mix i treat my goosneck flatbed and quad trailer once a year. Just let it sit a few days to dry. My trailers sit out in the AZ sun year round no cracked or rotten boards after 5 years.

linseed oil = spontaneous combustion.
