I really like this show! I try to make time to watch it whenever it's on TV. They've built some amazing tank creations. I especially like the ones with the 3-headed dragon, Penn & Teller's double tank, and the huge arch of a tank in a Las Vegas casino. I do have one question...where can I find the formula for Redneck's Grandmother's stain remover? He demonstrated it in Season 4, episode 11. I can't find it in my searches online. Can anybody tell me how or where to find it ? I think you can leave me an answer on this forum.
