The items that I would have created are not stickers, they would be a polished cast metal meant to cover the original sticker temporarily. The original sticker is stuck to painted aluminum, that you can access the back side of, where you would put a couple of strong magnets to hold the metal cover of your choice in place.
Michigan is not a state that requires annual inspection, so I have no worries about removing the sticker. This whole idea came from a discussion that I had via email with someone who received our MOG clubs newsletter, who was rather sure his state required that all manufacturer safety markings needed to be intact upon inspection and was looking for a way to cover the safety sticker temporarily.
Here is a list of every state that requires some sort of an inspection, if your state is in the list it is up to
you to know what is required come inspection time:
Alabama, Connecticut, Delaware, Hawaii, Louisiana, Maine, Maryland, Massachusetts, Missouri, New Hampshire, New York, North Carolina, Pennsylvania, Rhode Island, Texas, Utah, Vermont, Virginia, West Virginia, and Puerto Rico all require a minimal of one inspection per year (some every 6 months).
