Roofing tarpaper is virtually identical to the original stuff that GM used.

I used a sheet of DynaMat on the top of my tanks. And yes, it does manage any tin-can drone.

You could use DynaLiner if you wanted to, but it won't manage any tin-can drone, only manage heat.

Technically, where one would want 'insulation' would be on the bottom of the tank, to manage radiant heat from the asphalt. But most don't want anything that's visible. Everything else is strictly for anti-squeak as the body flexes.

With EFI, there's less issues with the tank/gas itself of getting super heated, due to the psi.
