Teak Bench Linseed Oil. Drying time can last up to 8 hours and one 32 oz can of oil comfortably covers 170 square feet of wood. This teak oil is popular for treatment to replace the natural oils in the teak bench removed by weathering.
Cedar is pretty oily wood, so that helps. If you want a long lasting durable good looking finish use sikkens novatech/novatop after thoroughly degreasing with acetone. The “teak oil” you buy in a store or online contains absolutely zero oil from a teak tree.
