GF's Exterior 450 Stains are low VOC premium quality, exterior pigmented water-based wood stains designed for outdoor projects with vertical surfaces such as garage doors, entrance doors and furniture.
When comparing General Finishes Outdoor Oil and Exterior 450 outdoor water-based topcoat , there are several key differences to consider:
Outdoor Oil:
Exterior 450 Topcoat is a tintable 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.
We recommend waiting 5-6 days to let the finish cure a bit before putting outdoors. The finish will continue to harden for approximately 20-21 days.
General Finishes Outdoor Oil is an exterior-rated penetrating oil that is a wood maintenance preservative. It contains UV prohibitors, heat stabilizers & mildew prohibitors. Use Outdoor Oil for all exterior outdoor wood projects, particularly wood furniture.
General Finishes NEW Exterior 450 White is a water-based exterior-rated pigmented coating for use on vertical surfaces such as outdoor kitchens, entry doors, garage doors, and windows.

Outdoor Oil works by saturation. Once the wood is thoroughly oiled then wait 24-48 hours before applying oil base. Use an exterior oil varnish. Do not use a water-based finish such as Exterior 450 Topcoat.
