So, I got 303 for Christmas. I got the vinyl package (cloth top/vinyl cleaner, and aerospace protectant). Now, I know these are noob questions, but I'd rather be safe than sorry:

I should use the cleaner first, then the protectant, correct?

Are both these products safe to use on the leather seats?

Are both these products safe to use on plastic?

 

Should be safe on plastic, vinyl, and leather

I only have the protectant but I believe it also cleans too, as I have used it as an all-in-one type product for my car.

 

I have still yet to try some of this stuff, Will it work on the interior black pieces around guages/ A/C radio ?
