Has anyone used this instead of liquid mask or rubber cement. i found some at Hobby Lobby today for $1.99. Its basicaaly like liquid mask, brush it on, let it dry, paint over it and peel. I didn't buy any yet, just wondering if anyone else has. And speaking of Hobby Lobby, I can't find any model putty and the people I asked didn't know what I was talking about. Should it be in the section with the models or over by the clays and fiberglass casting stuff?
