After Market - Do You Really Need that Rust and Dust?

By: Roosevelt Gist

When was the last time you saw a commercial for rust proofing? Auto manufacturers treat and seal most metal parts during the auto assembly process. I've been told that introducing a secondary rust proofing process will induce rusting because the metal
has been penetrated in the injection process; and, depending upon the uncontrolled environment in which the procedure is done, moisture can be trapped between the metal and the rust proofing product.

Paint sealant is an extraordinary product. You can easily maintain that new car finish for years if it is applied properly and reapplied when needed. Most minor scratches are not seen. The Teflon based paint sealant makes car cleaning a breeze
and protects the car from the elements. You can wipe away bird droppings and road tar with very little effort. But, the real question is do you have to pay a dealer $895 or more when a $4.50 bottle and some of your time will do the same?

Undercoating has been marketed by dealers as a cure for road noise. The product is sprayed over the undercarriage and has a sticky tar like appearance. Again, auto manufacturers do an excellent job in applying protective coatings and treat the metal
during the assembly process. If undercoating is done in an uncontrolled environment moisture will be trapped and over time will cause damage.

After market products can be beneficial in maintaining the appearance of your new vehicle. But, dealers can apply all these products for a combined total of approximately $150 or less. It's in your best interest to read the owner's manual to find out what protective measures the manufacturer has taken, what and how metals were treated and what is the recommended method for upkeep.

Questions to ask the salesperson: Why did you apply the protective package to this vehicle? What protective measures have the manufacturer taken? May I see your application area? Does it really cost that much to apply these coatings?
