Stop in for a cup of coffee

Was considering using a bicycle inner tube cut to size to replace the old rubber insulators on my fuel tank straps, any other ideas for that or for the top of the tank, other than ordering from a supplier like Classic?
I don't think mine had anything on the straps and pretty sure I put them back that way. Original top was like really heavy roof tar paper. I glued 2 layers of EPDM roofing together to replace it.
