in 2001, i bought a 96 ram with rust under the driver side door. no holes, just some minor blistering insdie the door and a little paint off on the underside of the door along the rocker. i treated it with a full application of Krown every fall for the 10 years I owned her, and the rust never got any worse. Krown literally stopped the rust dead in its tracks. Krown is the way to go.
