Syracuse (WSYR-TV) – NewsChannel 9 viewer Laurie is thinking about rustproofing her car to protect it against the salt, snow and ice. She wants to know if it's worth the money.
Automotive expert Herv Forward doesn't think so. He says today's cars are so well-preserved that added rustproofing is generally not needed.
Moreover, the holes that are drilled in your doors to complete the application will void a lot of warranties and the spray can trap old moisture and filth, so the finish actually corrodes faster than it otherwise would.
Cars manufactured 15 to 20 years ago might benefit from rustproofing, if done properly. However, he says, your money is probably better spent elsewhere.
