Can any one tell me what that black rubbery stuff is that is used to waterproof where the wires enter the indicator mounting tube ?I need to get some.ThanksRoy.
I thought that was for exhausts ?
I think you will find Gun Gum was the original product whic was applied with a calking gum , also used to cover welds prior to painting in place of grinding them to dress them.Dum Dum I think was a similar knock off product.
