− | Rust is a kind of corrosion | + | Rust is a kind of corrosion -- a decay or breakdown of a material in reaction to its environment. Specifically, rust is an electrochemical corrosion that occurs in the presence of iron, oxygen, and water. Oxygen and water are available in the open air, and iron is the principal ingredient in steel. |
For rust to occur it needs an anode (a piece of metal that gives up electrons), an electrolyte (a liquid that helps transport electrons), and a cathode (a piece of metal that accepts electrons). The more conductive the electrolyte, the quicker rust will occur. For this reason, humid air, salty air, or salty water will accelerate the formation of rust. | For rust to occur it needs an anode (a piece of metal that gives up electrons), an electrolyte (a liquid that helps transport electrons), and a cathode (a piece of metal that accepts electrons).

The following are not to be used as metal cleaners: lacquer thinner, acetone, reducers. Use the product within the recommendations of your product system. Cleaners typically vary as to strength, and time they take to evaporate. | The following are not to be used as metal cleaners: lacquer thinner, acetone, reducers.

One technique that has been recommended is to grind/clean the rust, tape the underside of the panel to be patched, and then fill the holes with fiberglass resin, then paint and undercoat. This trick is not really a good idea -- when the body flexes, there will be cracks in the fiberglass pieces. Metal also expands at different rates than [[Fiberglassing|fiberglass]], causing cracks to form, allowing more rust to form in these cracks. | One technique that has been recommended is to grind/clean the rust, tape the underside of the panel to be patched, and then fill the holes with fiberglass resin, then paint and undercoat.
