I respectfully disagree, undercoating just makes it worse. It is pretty well known that spraying off (washing) the salt spray is what works best. Using undercoating is old school, like changing oil every 3000 miles regardless. Made sense in the 50s/60s/70s but we are currently way beyond the usefulness. Oil change and undercoat shops like to scare customers into generating business. There may be exceptions, but the WK2 is not one of them.

I've lived and owned many a high mileage vehicle in salt country for 45 years now and getting the nasty stuff washed off is by far the best practice and the only practice that works long term. Getting the vehicle into a garage and dried out helps a lot. The vehicle you were looking at may have never been washed.

You will always get what looks like surface rust on drivetrain and suspension components but that doesn't hurt anything.

I undercoated and rust protected the heck out of my 79 CJ using top shelf products and it still crumbled away.

We don't all have garages, and I'm not taking my vehicles to an underbody car wash constantly through the winter. So I will continue to undercoat them and avoid rust through. And I didn't realize that steel stopped rusting after the 70s.

I respectfully disagree with this. I have no experience with Chrysler's and undercoating vs not undercoating but with Ford and gm products my family has always undercoated our vehicles, if you look at ours vs other the same age and mileage there is zero rust except of parts that cannot be undercoated. The vehicles that are not undercoated are rusting out already and these are vehicles from the late 90's and the early 2000's. We wash our vehicles around once a month to 2 months and once a year wax them with cheapo turtle wax. I'm sure everyone's results may vary but I know what works for us. For $300 I think it is cheap insurance.

If you iive in the Florida Keys, you will be driving a rust bucket in a few years......no matter what your ride unless U own a car wash. Love bugs do a lot of damage also and are hard to remove. No matter what you select and what your ion about this topic, I believe the only partial answer is good care. Sprinkler systems may leave deposits like calcium and the elements will in time get to your paint job (some colors worse than others). IMHO the dealer paint protection is a waste of $
