Which one do you guys think is better getting a truck under oiled or using a electric rust proofing device. Dealer is pushing the electric device but has not told me the cost of it yet.
How much does it cost to apply annually? How intricate is the application, do they get everything, or just the main undercarriage?I have done a lot of research on this subject. Attached is a link which does a comparison study between oil spray and electronic rustproofing. Eccles Auto Service - Complete Vehicle Service Centre in Dundas & Hamilton Area :: Do electronic rust protectors work?. I can only speak from my experience, but I have used Krown rustproofing annually on my last vehicle and it still looked new after 14 years of ownership. Not only does the product protect your under carriage, it also lubricates all your components(suspension,etc) and your exhaust system. I just replaced my car with a Ram EcoDiesel as I needed a larger vehicle and intend on having Krown applied annually. If you plan on keeping your vehicle for an extended period of time, rust proofing every year is money well spent. It saves you from having to do bodywork and keeps your vehicle looking new which results in a higher resale value.
Hope this info is of assistance in helping you make your decision.
