Not true. You might get away with that for one extra season (if you
have carefully kept everything covered with that lovely blue canvas -
which you have already told us is necessary for varnish because it
offers very little protection of its own)

Total BS.

I agree, that's why I called him on it!

No, I called it first, on you!




Here are a couple of things you don't know: Clear Varnish may contain
some form of UV protection or stabilization for the_varnish_itself,
but does almost nothing to keep the underlying wood from being damaged
by the sun. That's why you have to strip it all off every few years.
The wood has still taken a beating.

You're back peddling now. First you said : "which is why you have to
scrape and
sand it off every time you want to refresh things."
Now it's every few years.

Are your thought processes really this disjointed? Or are you simply
being intellectually dishonest?

Say that again. Only this time, look in the mirror.




To protect the wood REQUIRES some level of opacity, and the more
opacity, the more protection. That's why you have to cover all your
wood with canvas. I don't cover any of mine. That's because my wood is
protected by the finish. Yours is not.

Canvas are used to prolong the life of the varnish. And extend the
time between recoating. Not so much to protect the wood.

Doesn't matter precisely what the canvas is for.

It does in the context of the discussion we are having. Talk about
intellectually dishonest.


It's needed when
varnish is used, and not needed if you use Cetol.

Canvas will prolong the life of either finish.
