It’s never too late to start rust-control. It’s what you can’t see that should concern you so there should be no question about it.
Despite advances in manufacturing, rust remains one of a greatest enemies or a car — new or used.
Rust is generally more damaging to a car’s appearance and value than to its ability to get you where you need to go. It’s expensive to repair well on any vehicle and nearly impossible to reverse.
Rust control has changed over the years, but the concept is basically the same: keep moisture away from metal to prevent corrosion.
Prevention is always cheaper than cure, and your car is no different. The thing about rust? It starts in places you can’t see, and it starts long before you know it. When we think of rust and cars, we often imagine the days when nobody thought that their car would rust, they only wondered ‘when’. As manufacturers have moved more alloys and galvanized steel and zinc coatings, they’ve been able to guarantee (to five-years) that your ride won’t rust. While it’s true from the outside looking in things are much improved, if you put it up on a hoist, you’ll get a whole other story.
