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.
