It is black and I used black CT1, seems strong but not exactly perfect finish. Have also used it on a couple of plastic mirror back plates on a tractor and tele handler.
From the above it would appear to be trial and error but I feel still a better way than trying to use adhesives in which I have never had much faith, I will give this type of repair another go in the future now I've had a dabble at it myself.
