Minimum 2 coats. Use 30-35 lbs pressure for normal gloss. Thin only with POR-15 Solvent , if necessary. Never topcoat a POR-15 surface that hasn't cured, as this will ruin the coat already down. Moisture will shorten the life of unused POR-15 .
Seal can or jar immediately after using.
Rust is caused by moisture coming in contact with metal, which causes a chemical action called oxidation. All paints provide a measure of protection for a while, but since they are eventually softened and weakened by moisture, it is only a matter of time before moisture penetrates the painted surface and attacks the metal below. POR-15 is strengthened by exposure to moisture. Notice the hardness of the POR-15 coating. It doesn't chip, crack or peel like ordinary paints do, and its hardness will resist the wear and tear of everyday life.
