Product Description

The RUST-OLEUM 9331 is a gallon of Varathane satin exterior oil-based premium spar urethane, formulated for wood surfaces exposed to outdoor conditions. This coating provides UV and weather resistance, protecting decks, doors, windows, sills, and other exterior wood from sun damage, moisture, and general weathering.
