Sprayed on and they peel off when you don't want them anymore!
The key is putting on at least 5 coats, if you don't they peel off in little bitty pieces.
It you put on 5 or more coats, it peels off in one really tough sheet of rubber!
Mask off the area and peel off the masking tape away from the area as soon as the last coat is sprayed.
