Lizard skin mixes like cake batter. You should mask off where you don't want it, but overstay is minimal. Water based too, so not much smell. I am sold on it. It also tightened up the roof metal. Absolutely no oil canning with it on. If your roof needs filler, the roof will stay put while sanding. I have no affiliation with the product, just happy with the results. I used the heat and the sound killer.
