General Finishes Exterior 450 Clear Top coat, Quart

$31.43 ~~$41.9~~ In stock

Exterior 450 Topcoat is a clear-drying finish suitable for vertical exterior surfaces, such as fences, patio furniture, garage doors, entrance doors and interior windows. It is not recommended as a deck finish. This will provide outdoor woodwork with a tough, protective finish that will withstand the rigors of sun, rain, and wind. Exterior 450 is fortified with UV absorbers to stabilize the finish and built-in mildewcide to retard mold and mildew growth. It performs well as a clear coat or as an optional topcoat over General Finishes Milk Paint.

Matthew C. ★★★★★ Oct 22, 2026

Two coats on my patio table legs and they’ve held up through a rainy week without any clouding or peeling. The clear finish dried fast enough that I could put the furniture back out the same afternoon.

Charlotte O. ★★★★★ Oct 20, 2026

Used this on a set of French doors that get full afternoon sun, and the finish has stayed crystal clear through two rainy seasons without any peeling. The self-leveling really helps avoid brush marks on vertical surfaces—just apply it and walk away.

Used it on our cedar fence gate last spring and the clear coat still looks fresh through two snowy winters. Dries crystal clear without that yellowed plastic look, and it held up fine on the vertical slats where I was worried about runs.
