Renegade,

The black pinstripe is Sig 1/8 black pinstripe tape. Our good friend Ron Van Putte had a supply of the stuff; I think we've depleted his stock. It's sticky enough to lay down but ultraviolet sets it. We've used clear fingernail polish or clear butyrate to seal the ends so they will hopefully stay down. With use though it does come off, especially if fuel residue is left on the surfaces between flights.
