My father built a solid round redwood picknictable 35 years ago.I have
sanded it a half a dozen times,along with the 5 benches that go around
it.My problem is what clear finish to put on it.We have tried many
things,but the summer sun makes them yellow and peal.The first sealer
was a varathan product that worked very well for the first 20 years{it
is hung in the garage over the winter}but like all paint type
products,none are as good as they used to be.Any help would be
appreciated.


Like all type paint products none are as good as they used to be. Hummmmm..


You mention a clear varnish that does not hold up as well as the paint
product that held up for 20 years.
Paints hold up much better than clear varnishes when exposed to sun light.
Paints hold up better because they are opaque and do not let sun light
totally penetrate the finish.

Your best varnish is probably going to be a Spar varnish, but be prepared to
refinish ever few years.
