I realize this thread is LONG dead, but I need to make some repairs to my STA, and I need checked covering (or else I have to cut and stick LOTS of black squares...). I've looked around, but I can't find anyone making it with 70mm squares like the wing bottoms came covered with. Anyone know of a source? If not, I'll have to strip the whole thing and start over with 2" or 4" checked Ultracote, neither of which will look as good...
