Cetol Door & Window Finish is a translucent coating that maintains the beauty of exterior wood surfaces better than polyurethanes or varnishes, says the maker. The high-solids alkyd formulation contains ingredients — like iron oxide pigments and UV absorbers — that help it stay flexible and resist sun damage. It comes in two clear sheens (satin and gloss) and four colors and costs about $65 per gallon.
