I need some thin sheet metal to cover some panels on a dirt track car, but we're having trouble finding inexpensive sheetmetal in this area. I was quoted $120 for a 36X50 piece at the last place I called. I'm looking for one 70X30 piece or two 45X30 pieces of very thin sheet metal. All 3 of the hardware stores in town said they didn't have anything that would work for me. Is there a place online or near San Antonio that I could go to?
