Took a fair amount of time before I summoned the courage to attack the wings but once I started there was no turning back.
Used an angle grinder with a slitting disc to remove the baulk of the material then finished it of with my die grinder. Had a couple of small bits to touch in, painted it with a fine brush then flatted back and polished.
Quite happy with how they look, I was originally thinking of painting the black part body colour but decided to leave it as it is for now.
Just need to get a couple of badges made to replace the M3 ones.
