Built four large white oak chairs about 3 years ago for my daughter for her back deck. They sat outside, sometimes covered, sometimes not. Now I'm sanding them down to smooth the raised grain and was going to use SuperDeck transparent oil on them. I have used many gallons of this in the years past at my cabin in the mountains on the siding and deck and was very pleased with it. Found out it can't be sold in Calif anymore. Anybody in Calif have any suggestions of what might work that they have used (that's still sold in Calif)? Are all oils banned? I don't want a surface finish. Tx. Randy
