Putting a lid on it is a good idea because the acetone will evaporate. I did this in my garage and just left the door open for an hour or so the next day and it aired out nicely.
By using the kyosho or similar steering rods you can get even more steering. The ends are shaped like hockey sticks instead of straight which allows it to travel farther before hittind the a-arm.
You can get a gallon of acetone from your local hardware store. Soak tires in this overnight and it removes the tires and the glue. The acetone eats the glue but doesn't hurt the tires or rims.
