“I used a protectant from a different manufacture for many years. Inside the car on the dash, various plastics and also the engine bay. I decided to use 303 as I had read that it was non-greasy (the other product was very greasy) and it certainly proved to be that. It adds a protective layer and adds a soft sheen. Great stuff.”
“As title. Spray on and leave or use microfiber to spread. Handy for complex bumper inserts/grilles just cover and leave. Wipe excess off. Super useful for engine bays, leaves a nice non shiney finish, a nice oem look once dried.”
