Make painting projects flow more smoothly by using Penetrol oil paint additive with oil or alkyd paints. Penetrol reduces brush marks and leveling problems with the paint and reduces fatigue and frustration with painting projects. Penetrol will not cut or thin the paint as paint thinners do and will maintain and fortify the qualities already inherent in the paint.For use with exterior (only) oil-based paints and stains Helps paint flow better, allowing you to paint without brush marks Increases paint adhesion to prevent peeling and blistering Helps improve oil-based paint and primer penetration Conditions metal to stop rust and prevent oxidation Conditions fiberglass to restore color Addition of Penetrol oil paint additive will not change paint appearance or quality like ordinary paint thinnersFeatures:Exterior use only In oil-based paints: for coating exterior trim, molding, doors, furniture, plywood, metal In oil-based primers: for coating exterior bare wood or metal To condition bare or rusted metal: use on steel, garden tools, outdoor furniture, brass, aluminum and chrome To condition fiberglass: use on fiberglass surfaces and boatsApplication Tips:Always mix a small amount of Penetrol oil paint additive with the paint you are using to determine compatibility. If paint is thick, or in extreme hot or cold temperatures, more Penetrol may be added (up to 2.5 pints per gallon of paint).ORDER IS FOR ONE (1) GALLON
