I just bought a Brinkman charcoal smoker for $20 only used once. Friend had it and hated fooling with it to keep heat up so I offered him $20 and he yanked my hand off. He had the water pan and charcoal pan backwards so there is a small hole in the water pan now that I am going to have to fix. Any suggestions on how to repair a small hole less than 1/4"? Did I make a fair purchase or did I get burnt? Thanks....
