| Does anyone know if those electronic rust proof gadgets work as a rust proofer on autos ? Or is getting it undercoated a better option ? When I buy a auto or truck it has to last a looong time, that is why I inquire. |
| The ones I am talking about send a small pulse of electric through the sheet metal which I am told excite the molecules of metal and in turn prevent surface rust from forming, they use a similar thing on bridges to prevent rust, that is why you see those solar panels by some bridges. |
