This specially priced kit includes 1 gallon of POR-15 Cleaner Degreaser, 1 gallon of POR-15 Metal Prep, and 1 gallon of POR-15 Rust Preventive in Semi Gloss Black. Sold together as a kit only in this listing. Please see our other kits for more bundled options. POR-15 recommends after opening up a can, place the unused portion of the can to be stored in a plastic container. The cans from POR-15 are air tight and once opened, you will damage the lid and/or can. As soon as air enters into the can, it will cause the paint to cure, making reopening of the can with the lid difficult. After opening the paint, any paint on or around the edges of the lid will weld the can closed.
