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.


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.


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.
