About WOODLIFE® Classic Clear Wood Preservative Prolong the integrity of above-ground outdoor wood with Rust-Oleum® Wolman™ WOODLIFE® CLASSIC. This 100%-clear formula repels water and contains nearly double the fungicide of standard sealers or stains. Use it as a final finish or primer. EPA-registered, fungicidal preservative protects against surface mold, mildew, rot and decay. Water repellent resists water damage: swelling, warping, end-checking. 100% clear – reveals natural wood color and allows it to gray naturally.
