Where can I find filler putty?

You can use automotive glazing or spot putty which is available at any store that
sells automotive paints. You can get a lifetime supply for a little more than the price
of a small tube of modeling putty at your local hobby shop. It comes in red or green,
is easily sanded and, takes paint very well.
