Rat's Glass was founded by George Long, a.k.a. "Rat", in Friendsville, TN a few minutes south of Knoxville more than 30 years ago. The company has 10 distinct models of hot rods from the classic '32 to its award winning Speedstar.
In 2018, George sold Rat's Glass in its entirety to the crew at Factory Five Racing. Factory Five plans on maintaining Rat's Glass product lines.
