Cuprinol in some awfully good stuff. The green color preservative IIRC
is guaranteed against rot for 20 years if you just soak the luimber
with it first, but I have used it since the early 70's, in the green
color as well as their other colors and its super. I went to Avon
Conneticut one time to pick up a load of Cuprinol at the factory
there, and they had all these various samples of just brushed on wood
with cuprinol and others that were just soaked for various time
periods all out in their test yard, and it all looked great. Back
when I made that trip it was not available in our area, and it was
cheaper and faster to run to Avon, Conneticut and pick up a pickup
truck load than it wa to have it shipped. I was introduced to it when
I did some work in a marina in New London, Conn, as it was very
popular way back then for use in marinas and docks etc.
