Exterior 450 Topcoat a clear-drying low VOC finish suitable for vertical exterior surfaces, such as fences, patio furniture, garage doors and entrance doors. It is not recommended as a deck finish. Exterior 450 is fortified with UV absorbers to stabilize and protect the integrity the finish*, and built-in mildewcides to slow mold and mildew growth. It performs well as a clear coat or as an optional topcoat over darker color General Finishes Milk Paint**. Do not use over light or white paints as yellowing may occur.
Exterior 450 Topcoat is not intended for decks. It can be used on tabletops that do not receive direct exposure to sun and rain. As with all fine furniture finishes, wipe up spills in a timely manner to protect the finish.
Don't forget your brushes and sandpaper!
*The UV additive in 450 Clear will protect the integrity of the film, but will not prevent the wood from changing color from sunlight. Brush or spray.
**Do NOT use Exterior 450 or any other clear coat, over white or light paints such as GF Milk Paint, or GF White Poly as it may cause yellowing. Any clear coat can become reactive over wood substrates or existing finishes, causing tannin or dye bleed-though regardless of priming. All of GF's white paints do NOT require a topcoat.
Note: Exterior 450 is designed to let the water permeate the finishas it dries, the water releases back out to allow the finish to tighten down again. Temporary cloudiness may occur as the finish dries. The UV additive in 450 Clear will protect the integrity of the finish, but will not prevent the wood from changing color from sunlight.
Warning: We do not recommend Exterior 450 stains or topcoats for exotic woods Ipe, Teak, or other dense oily woods that will get exposure.

Finally after 17 years and 7 re-do's of the doors, this product is showing that it's going to hold up longer than a few months. I'll know better the outcome after the winter of 22'.
