What is this por-15 stuff, how can it help me get rid of the rust, will i still have to grind down the rust or what?
MANY PRODUCTS CLAIM TO STOP RUST; SOME ARE PAINTS, SOME ARE CONVERSION PRODUCTS, SOME ARE RUST TREATMENTS. NONE SEEM TO REALLY STOP RUST PERMANENTLY. WHY IS POR-15 DIFFERENT, AND WHY SHOULD I BELIEVE IT WILL WORK ANY BETTER? 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- hard, non-porous coating that won't crack, chip, or peel. It keeps moisture away from metal with a coating that is strengthened by continued exposure to moisture.

try to get some of that rust avenger I posted about here. For a couple of bucks, you can take care of the problem rust. After that, if you want to take some touchup paint and color in the bare metal, you could. This is opposed to sanding down the area which would require masking and priming and spraying multiple coats of paint that IMO would never match anyway.fuhctious said:What about little tiny spots in your paint that may have chipped off and there is rust? I'm talking about really tiny flecks that may have gotten hit by a rock or something, not larger areas.
What is the best there, to just apply over the tiny spot, or sand away a small area and then apply the rust product?
