t-Natural-Coatings-PolyWhey-Exterior-Penetrating-Stain-Finish.And Rubio Monocoat Hybrid Oil--a zero-VOC oil-based sealer that comes in 22 colors: http://www.greenbuildingsupply.com/All-Products/Paints-Coatings-Wood-Stains-Sea
lers/Rubio-Monocoat-Hybrid-Exterior-Wood-Protector.Both products are available in clear, however, darker colors contain pigments that block UV light much better and prolong the finish by a factor of 2-3 times. Our testing confirmed that both products held up just as long in Iowa weather.
