Good morning folks, whenever I see someone posting inaccurate information about rustproofing, I need to speak up. Over the last few years there's been an explosion of people getting into the "undercoating business. Most do a great job, some not so much. Anyone that tells you how long a rustproofing will last doesn't know the business. Everyone uses their vehicle differently so the timing or a reapplication will vary. In most cases a 12 to 18 month schedule will work but if you put a lot of miles on during inclement weather 12 months is most likely. What's more important than that? The timing of the application is important. While applying any undercoating will be better than nothing having it done in the winter months is not as beneficial as having it done during the warmer months. Temperatures play a role in the formation of rust. Parking your car inside of a heated garage during the winter will increase corrosion, vehicles left outside will freeze the moisture stopping the corrosion. Having said that most of the deicing agents used today lower that temperature greatly in some cases down to nearly 0 degrees. Are you totally confused yet? The best thing to do to protect your vehicle is to talk to a knowledgeable applicator, discuss your driving habits and they will be able to advise you of the best way to proceed.
