I had loaned my 686-6 to a friend of mine for an extended period. He and his wife is a smoker. When he brought the gun and it's case back to me it wreaked of smoke. I cleaned the plastic and took the foam out of the case and cleaned it as well. I put the cleaned foam outside on the bench to dry and air out. In the meantime my wife put the dog out in the yard, and you guessed it, he shredded my newly cleaned foam. Where can I get similar foam to replace in my case?
