How long does Protect All® All-Surface Care last? How often should I use it?

An application will last up to six months depending on climatic conditions and exposure to the sun. However, you may use All-Surface Care as often as you like with no excessive build-up. Use it regularly to keep maintenance to a minimum. It’s easy, quick, and you are polishing and waxing every time you clean. All-Surface Care works best at temperatures between 60 and 90 degrees Fahrenheit. Keep All-Surface Care from freezing.
