I just purchased my first ever brand new car (Acura MDX in Modern Steel Metallic, a dark grey color). I`m interested mainly in keeping it protected through the harsh winters here in New England. I drive a lot in bad weather and my old car got a ton of salt, etc, and I won`t be able to wash outside for the duration of the winter. I have been reading about Optimum gloss coat and I`m thinking about giving that a try.

I purchased Optimum No Rinse and Wax and Optiseal and I cleaned the car with a bunch of microfiber towels I bought from Costco. It wasn`t all that dirty, and now it`s nice and shiny, and hopefully a little protected with the Optiseal.

I`ve been watching Youtube videos on the paint preparation phase.

It seems like most people advise doing some sort of decontamination even though the car is brand new. I don`t understand if I am supposed to use something like Optimum Ferrex or the clay towel or both?

Also, do I really need to purchase the Porter Cable 7424XP and polish the whole car before adding the Gloss Coat?

Any other products that I definitely need for this? Thanks!
