Quite simply, rust sucks. Most any vehicle regularly driven during winters in the Salt Belt will fall victim to corrosion, and the various spray-on undercoatings available from the aftermarket have their shortcomings. Specifically, the spray-on application of these coatings often results in incomplete coverage, and what is applied will typically degrade upon repeated exposure to a decade's worth of abrasive road debris.
After dropping the fuel tank on our 1996 Buick Roadmaster, we found some oxidized ugliness despite the vehicle's near-impeccable maintenance record. Fortunately, the damage was caught before significant amounts of sheetmetal were lost, and modern technology has provided us with the tools to keep the situation from getting worse.
