It will fill in holes better than black or clear. Silver contains metal filler and should be used in badly rusted, pitted areas. Which POR-15 (Black/Silver/Gray) should I use? Clean metal first with POR-15 Marine-Clean, then rinse with water and dry. This finish must be removed before using POR-15 or Metal-Ready. NOTE: New steel is coated with a protective oil finish at the mill. It's a rust remover that leaves a zinc phosphate coating on base metal, the perfect preprimer for POR-15. But be aware that POR-15 doesn't contain styrene and thus cannot melt fiberglass cloth like polyester resin does. Use also with fiberglass cloth to make super-strong surfaces in rusted-out areas. It will adhere better than polyester resin and has greater strength. POR-15 is fully compatible with fiberglass and can be used to repair cracks in gelcoat. Can POR-15 be used with fiberglass?Ībsolutely. The more humid the area, the faster the dry time, which usually varies from 3 to 6 hours. That depends on the ambient humidity (surrounding area). First paint both sides of the rusted area with POR-15 then use body filler or putty as soon as the POR-15 is dry to the touch. Can I use body filler or putty with POR-15? Be sure to read thoroughly our directions and tip sheets regarding topcoating before using POR-15. POR-15 Tie-Coat Primer is the best prime coat to use before topcoating POR-15. POR-15 will accept all paints, including lacquer-based paints. Can I paint over POR-15 with other paints?Ībsolutely. POR-15 does not adhere well to smooth, shiny surfaces, but will adhere well to those surfaces with the proper preparation. Seasoned metal and sandblasted metal are also good. What is the best surface on which to paint POR-15? POR-15 is not dangerous if you follow our simple directions. That's why you must always paint in a well-ventilated area and keep your nose away from the paint container. Are POR-15 vapors dangerous to my health?

If POR-15 dries on your skin, nothing will take it off, and you will 'wear' it for 3 or 4 days until natural oils and flaking skin remove it. No, but if you do, remove it at once with solvent or lacquer thinner. Is it dangerous to get POR-15 on my hands? POR-15 can't stop rust if it isn't in direct contact with the base metal. You must remember that ordinary paints are weakened by exposure to moisture. Yes, but you will lose the important benefits of POR-15. You should use only POR-15 Solvent for thinning. How do I thin POR-15 if I want to spray it? Proper equipment and organic vapor particulate respirators for solvents are essential for spraying. Most people brush it on, but many spray also. It keeps moisture away from metal with a coating that is strengthened by continued exposure to moisture. POR-15 works because it chemically bonds to rusted metal and forms a rock- hard, non-porous coating that won't crack, chip, or peel. History of the failure of these products is well documented most simply don't work for more than a few months at best, and they are subject to the same chipping and cracking that occurs with ordinary rust coatings.
Rust conversion products claim to change the chemical nature of rust and convert it to a more stable element that won't rust again. It doesn't chip, crack, or peel like ordinary paints do, and its hardness will resist the wear and tear of every day life. Notice the hardness of the POR-15 coating.
POR-15 is strengthened by exposure to moisture. All of the so-called rust preventive paints on the market (except POR-15) are weakened by exposure to moisture.
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 Rust is caused by moisture coming in contact with metal, which causes a chemical action called oxidation. Why is POR-15 different, and why should I believe it will work any better? None seem to really stop rust permanently. Many products claim to stop rust some are paints, some are conversion products, some are rust treatments.
