Who has had their truck undercoated?

[AbramsM1]

Curios to see who had the dealer put the undercoating on your vehicle or maybe some other aftermarket type of undercoating. Whether it was rubberized or clear or whatever. Basically I want to see what the best product is for undercoating. Vehicles tend to rust mighty fast here in Minnesota. Regards, Abrams

I have the dealer applied undercoat for mine. It is clear, and they shoot everything!!!
Even the underside of the hood. I have to get it "refreshed" every six months, but living in northern Indiana, they use literally tons of salt on the roads, so much that they turn white when they start to dry out. Anything I can do to protect it, means it looks great for years to come. Once the cancer starts, no matter how little, there's no stopping it until new paint

I would reconsider. You shouldn't need any type of undercoating with the medals used in today's manufacturing. They are more likley to cause more damage than good.

Undercoating and spray-on type rust proofing (rustproofing) insulates the metal from moisture and oxygen by covering it with a protective coating.

It's effective as long as the protective surface is not damaged. In real terms this is not possible and where damage occurs, no matter how small, rust will occur. Cracking at the body joints, stone chips, scratches, peeling and brittleness of the undercoating can result in water getting trapped between the metal and the undercoating allowing rust to form where you can't see it until it's too late. This is why many rust proofing and undercoating companies recommend that you get your car or truck inspected and re-sprayed every year. This, of course, costs you more money.

You might want to check your warranty book again. I seem to remember reading something about aftermarket products voiding the corrosion warranty. (could be memory malfunction though, that's starting to go too!)
