I ordered a new Tacoma in celestial silver. I have it narrowed down to either cquartz 3.0 uk or crystal serum lite. Should i consider topping those with their respective coatings, exo for csl and sic for uk 3.0 or should i just stick with the base coating? Should i use something like reload every few months or will it somehow interfere with the coatings? Do you have suggestions on something other than the options I have listed?
