so it appears there is no perfect outdoor finish.  even solid plastic will degrade over time in sunlight.  I think this is a good choice from all that we have and use it on most everything.  best on things that see occasional moisture and sunlight, and nothing can handle 24/7/365 over many years.  I am using it to keep the wood from rotting, not for the perfect wood grain, color ect.  although that is what we dream of.   :)

Bloxygen is on amazon and is argon.  we used to use something called trimix with Co2, argon and nitrogen gas for mig.

Well this thread got alot more responses and went in many more directions than I expected. Kind of exciting. I really hope all this information helps someone else. 

I am hoping to get the other side of the benches done sometime next week. I will take more detailed pictures and try to cut the glare so the detail shows better. As was mentioned earlier, the top side of the bench was prepped quite a bit better than the bottom side.

so went out and took pics of my 24/7/365 projects.



 
done about 3 years ago, defects in the wood (split) were already present



 

was new about 5 years ago.  the area of the house numbers, routed and painted, then covered with epoxy are where the worst peeling is.  the post looks like new.  the gray at the back corner is where I hit it with the grass catcher on the mower on a regular basis.



 

this is honey locust in the table frame (given to us) of angle iron that sits out by the pool.  3 years since redone.  could light sand or run through the planer, and recoat.  



 

close up.  it is the grain areas that degrade as they prob. hold the water.  makes me wonder if more finish might hold up better it the grain was fully covered until smooth.  very interesting thread.

@69bronco  what is that varnish? I thought spar urethane was supposed to be a good outdoor option. I use the flip and seal trick in PVC cement, it helps it last longer.  Still almost always have to run to town to buy some at the hardware because t h e old stuff is hard anyway...

Just used it (well this past winter) for our main pie hole fillin station. I put trice coats. Messed up, didn't thin it,so it's a tiny bit wavy, but for an old table that'll get tossed (I say tossed, I'm sure me bride will find a use for it) in a year or so, when the new digs are dug, it'll work.
Just have to look around the freshly churned butter stuff

Epifanes varnish is a good one, also I've had good luck with Total Boat brand. Just make sure it's spar varnish. Spar urethane is a polyurethane.

Anything exposed outside now I'm using ready seal walnut with used motor oil. I think trying to seal wood outside with a hard coat is a waste of time over all. Looks terrible when it starts to peal and peal it will. Looks great for a while, will grant you that.
