Why is rust on a car a problem?
Frame rust is a big concern, as it affects the integrity of the car. Bad enough frame rust can cause parts to snap off or crack, which will really compromise the safety of you, your passengers, and other motorists. It may also significantly diminish the car's ability to protect you in a crash.
How long do rust repairs last? It's impossible to stop it completely, but you can buy 6-10 years if repaired properly. That usually means welding in new sheet metal, sandblasting, priming with a rustproofing/rust converter primer, cavity wax that coats the inside of the car because cars rust from the inside out, regular primers and paint, and undercoat where applicable.
