White-Out.

I could understand being a business owner and getting upset when you find that your store has been tagged or vandalized in some other fashion. But for some reason I think that when you just throw up some white paint to cover said graffiti it makes the whole thing worse. Did Home Depot stop making the original color? It's like that old joke about knowing a blond has been at a computer because you found white-out on the computer screen. It's pretty much the same train of thought.
