afaik you just paint it over the rust you have and it stops further corrosion as well as puts a hard coating over it.
the site is www.por-15.com
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.

Actually there is a small retail product called Rust Avenger. I comes in an oversized ballpoint pen-like applicator. You dab it onto the rust and when it dries it turns the rust into a more solid stable metal with like a light epoxy finish on it.
At that point the rust is stopped and it is paintable. Only a few bucks at car parts stores.

go to www.eastwoodcompany.com and purchase the rust converter they sell there. It comes in red, black and silver. If you follow the directions and remove all scaled rust, it will stop the rust and prevent it from comming back. I have used the POR-15 on a the floor of a project of mine and 5 years later I was cutting the floors out to replace them. The stuff could work on parts that are absolutely dry but I had no luck.

The eastwood product is the only rust converter product I found that works.

Also, orison marketing from texas sells a solution for removing rust called evapo rust, but it requires warm temperatures and the part really needs to submersed in the product to work but it works better than sand blasting.

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?

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.
