Patton (P Glade) Glade
 

I got one of Patton's excellent gas tank pads. Before hearing from him, I was going to use roofing asphalt or something like that. Patton has a very nice item made from heavy material with the plastic lining, just like the original. Very reasonable pricing as well....For my location, it was $33 shipped.
He even included a totally unexpected bonus...a package of factory style chrome lower windshield stainless trim screws and factory style wire retaining loop for the sending unit wire.
Great guy to deal with!
