Under carrage salt removal

[Jamie42]

I believe that the action needed to remove salt should be based on the amount of exposure.
The best action is to prevent / avoid contact in the first place, for a car used on salt covered roads this is best done by the application of a protectant in the fall.

I undercoat my winter vehicles with a product such as Rust Check or Krown every fall.

When the salt season is over, the underbody rinse and salt neutralization is perfect.

This is variable by temperature, the worst situation being mild temps, and extreme cold rendering the salt ineffective.

Either way, SALT SUCKS.

I was looking at Krown - has it worked well for you? They say on their website that using it increases resale value: Krown Rust Control | The Benefits | Higher Resale Value
is this true? I like the idea of preventing damage before it actually happens but I also heard rust proofing can void warranties of newer cars that already have it - is this true?

What about taking something like this and just flipping it over? Ive been considering it but want to see how the water comes out first.

Krown is most definitely worth it. When I lived in Southern Ontario, the amount of salt that caked my car during the winter was ridiculous. I took my car to Krown before every winter from the time I bought the car (new). It was ~$120 for a treatment.

When I moved to Alberta, most mechanics can spot an Ontario car from all the rust underneath. First guy I took it to was actually surprised when I told him it spent 8 winters there. I just sold that car in January and after 11 winters, the car had almost no rust on it. Just make sure they're spraying inside the all of the panels, hood and trunk as well, not just the undercarriage.

Thanks Mike that's good to know. Cars are definitely rusty here, especially after winters like these.
