> 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. All of the so-called rust preventive
> paints on the market (except POR-15) are weakened by exposure to moisture.
> 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 every day life.
> Rust conversion products claim to change the chemical nature of rust and
> convert it to a more stable element that won't rust again. 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.

> POR-15 works because it chemically bonds to rusted metal and forms a rock-
