Have owned a lot of TR4s over the years. The car I have now is around CT 28000 and has blue tape, Had a couple cars around CT 12000 that had black tape,and a CT300? car that had cloth. If you're building a show car,some judges will probably find fault with anything you choose. I prefer the blue tape.Detail stands out better. Sorry if not much help,but Im sure the experts will chime in.
