Mad, if you can pick up the technique go for it. There are still people out there who think lead is the only way to go. Of course they have no idea how well today's polyester fillers really perform, but they won't let reality get in the way of their beliefs. One word of caution here. Breathing lead "dust" and fumes is not good for the old lungs, of course, neither is breathing "bondo" dust. So, do yourself a favor. Go to your nearest auto body and paint jobber and spend $30 on a good respirator. Tell them what you will be working with and they'll get you the proper filters.
