I tried using the spray-on colour, and it didn't look too bad... until it was paired with the wig. The colour difference was too vast to get away with, as you can see from the piccie.
Had a brief go at spraying my hair, figuring that that may work, but it just left my hair looking straight and flat. Father Christmas with long, flat, grey hair... No thanks.
So, the beard has gone...
