The fun begins here. Carmody grabbed the loudest air hammer in the shop, chucked in a chisel bit, and attacked the roof. Air hammers are the fastest way to remove large sections of metal you don't need to save. Start by hammering straight down into the panel, cutting a pilot hole. Then cut at an angle across the panel, peeling the excess away as you go.
We fully endorse the Facemelter air hammer grimace.
