When comparing General Finishes Outdoor Oil and Exterior 450 outdoor water-based topcoat , there are several key differences to consider:
Outdoor Oil:
GF recommends using the least expensive product that will provide the needed performance characteristics. We offer a range of products designed for professional spray applications and brush-on finishes for consumer use.
General Finishes offers a complete coatings system with a finish for every objective.
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.
