Here it is…

1.) Polishing is removing swirlmarks from the compounding process that you do prior polishing stage. swirl marks from the compounding chemical has abrasives that removes light scratch marks but produces swirlmarks. In order to remove this material you need polishing chemicals.

Wax is used AFTER polishing stage. This is done to protect the two process (compounding and polishing process you did on your vehicle) Usually wax life is around 3-4 washes. After that you need to reply it again.

2.)Detergent DOES NOT contain abrasives. Rather it has strong chemical formulation (high PH Level) that removes the oil (this time the wax applied in your vehicle)stripping it during washing. That is why it is recommended to use 3M Car care shampoo because its PH level is lower thus it is not harmful on the wax of the car.

3. Take note also that car wax will not have an effect with the sea breeze. you have the wrong information on it. The rust forms on the metal because of metal+oxygen and moisture combine. It is suggested that you use undercoating products on the under carriage of your vehicle

I believe on 3M Products. But you need to have the right information in order not to mislead others. I agree with your blog. But you really need to consult with the expert before you explain the facts of car washing.
