I use the 303 vinyl protectant on my interior plastic on all my cars. Doesn't leave the greasy shiny mess like Armor-All does. Plus, it has UV sunscreen in the formulation to protect interior parts from sun damage.
I use 303 Aerospace Protectant on all of my plastic, vinyl, and leather on the interior. I also use it on the exterior on all the plastic and rubber trim, and even sometimes on the tires. I also use it on the canvas of my tent beds on my hybrid travel trailer, and on the rubber roof. It's great stuff!
