Protection from corrosion.
Beneath the paint or finish of a car is a bare metal of a car body. We know that over time, paints and finish dry out, crack and peel. Once they do, the metal is exposed. To protect the car, a thin protective layer made of softer metal but is more resistive to corrosion, is deposited on the car body before painting. Thus making the car body more resistant to corrosion.
Add: why not make the whole car out of this less corrosive material? Because this material is too soft. So it takes twice or more amount of this metal to match the stiffness of current material used in car bodies. This would then raise weight and cost of the car.

It is important to clean, sanitize and store our equipment properly.
Explanation:Because we clean our surrounding for our safety from bacteria's. We sanitize to make it more cleaner or in other words to protect our health. We store our products properly so that it doesn't make any more trouble like we were finding something we use and our products properly stored and because of that you don't need to find anymore.
Hope it helps.
