The Rust-Oleum Outdoor Fabric Paint has excellent UV resistant properties and it's washable. For this reason, we do not recommend using a clear coat on top of the product as it will not hold up properly when washed. If additional protection is desired, consider using the Rust-Oleum NeverWet Fabric Water Repelling Treatment. For additional information, please take a look at the page below!
