Any opinions on rustproofing under a new Toyota? We were told by the dealer that they no longer seal and undercoat cars since 2009 because it saves the dealer money. Does anyone know anything about this or if it is true?
Sadly, we already bought the car. We only wanted the extended warranty. We specified we wanted the toyota brand extended warranty and when we got home and read all the paperwork he shoved in the envelope for us we found it is not the Toyota we were sold but a bogus company with all kinds of complaints Fidelity warranty service so we need to call tomorrow and try and cancel it if it is possible. We were debating on the rust proofing and thought we would research it first but I am only finding old articles pre 2009 on rustproofing and how it was not needed back then. My husband did look under the car and said only the wheel wells seem to be coated.
This is what Consumer Reports advises:
Dealer extras
Before they let you drive away, dealers may also try to get you to buy extra services that are usually overpriced. These include:
Rustproofing and undercoating. Don’t bother. Today’s vehicles are manufactured with good corrosion protection. In fact, Consumer Reports’ Annual Auto Surveys show that rust problems have almost vanished in modern vehicles. Standard rust-through warranties for most domestic and imported vehicles run five years or more, and many will cover you for an unlimited number of miles during the warranty period.

This really surprises me. I work in an auto repair shop in NH and we see a lot of rust on vehicles.
What we recommend here is to make sure that you wash your car regularly during salt season. We have a car wash in town with a good undercarriage spray. I do that on my vehicle once a week or so in the winter.
We also do seasonal under spray with an oil based product. Depending on the vehicle it might be just brake and fuel lines, or the whole frame. We are using a product called Fluid Film mostly. It's lanolin based.
It's important to keep a regular eye on the underneath of your car. It's easy to prevent rust from being a problem, but once it starts it is amazing how fast the rust can spread.
