Does item quality decrease over time?

In Counter-Strike: Global Offensive, I have an "AUG Hot Rod: Factory New" Skin. Each skin in CS:GO has it's own quality, and each quality looks different (Ex. Well-worn may have paint peeled off).

If I use my Factory New AUG in CS:GO, will the quality decrease, or will it stay the same?


Solution 1:

This guide says no:

As you can see, Factory New has the freshest looking paint job out of any of the item exteriors. The item exteriors will not degrade over time. They are simply another variation of weapon finishes.

Solution 2:

They do not, the weapon condition stays the same, and does not degrade over time.
