Well I saw a bunch of pics of her "defaced garage" that really made it seem like some sort of stencil / guard was used; there didn't appear to be any spray paint on the brick - only on the garage door & trim immediately surrounding it.

You could literally see the line, just as if someone had taped it off like you would if you were painting and didnt want to get paint on a certain area.

It definitely seemed very odd.....

Pics weren't clear enough for me to be 100%, but knowing who we're dealing with here....
