....that may be of interest to woodworkers.

In the video, they are restoring a weather checked dinghy seat but, it would work as well on new wood that may be exposed to the weather. 

And, I'm wondering if it could be used on a bar or counter top. Certainly useful on any project where you'd want a super durable finish.

I've seen a couple of really "weather worn" oak entrance doors. They faced into the sun for at least half a day. This might just be the finish for such a situation.

I have tried a penetrating epoxy that was supposed to go oh so deep into the wood and seal in rot and encapsulate it killing the mold spores etc etc yadda yadda yadda.

It was all marketing hype.  The stuff doesn't penetrate. I even thinned it with Naptha which is better than alcohol as alcohol actually interferes with the catalysation of the polymer molecule.

Thinning the stuff is a misnomer .  The molecule is a certain size and all you can accomplish is a lessening of the viscosity, but you can't make the molecule smaller so the thinning agent may penetrate like blue blazes but the molecule of the product can only go through a pore that is large enough to let it pass. 

Then it sticks in pores that are large enough thus making the pores smaller and not letting more of the product pass.

It's like adding water to gravel and hoping that the water will make the gravel penetrate something. It won't.

Anyway I soaked wood in the stuff literally submerging it in the stuff for hours.  Then I  took it out let the stuff complete  the curing which took longer than overnight and afterward I sawed the stuff up to see what I had.

In pine it really didn't penetrate at all.   It did enter the end grain a little bit like  1/16" to 1/8" in spots.

So be warned, it does not do what the marketing hype says it will do crusty sailor Bill or no.  It might make a nice pre-treat and sealer and it might hold on better than varnish or paint, but that's about the best of it.

Cliff, I know of no product that will penetrate and seal/encapsulate rot within the wood without the use of a vacuum bag. 

However, I used a similar product, also from the same company, on a set of redwood steps with the intent of protecting it from the ravages of the snow and rain. No varnish over it. 

Six winters and they remain sound and look good.

That's impressive. Is it slippery when wet?

I did a whole 20*40 deck in a two part urethane I got from EpoxySystems and  it held up to almost 15 years. The only down side was color choice stunk ( safety white) and it was very slick when wet.

I was a bit. It's a summer cabin, though. Were it a year round residence, I maybe should have added some non slip grit.
