Hi Nick
I had both front wings and both rear wings off the car back in Dec 17. Shot blasted back to bare metal to remove all the rust, then re-primed, undersealed and re-sprayed. They are perfect! The colour match is superb and they look fantastic. Also had a new radiator core fitted at the same time. Labour costs are quite high because the upper surfaces of the wings need lots and lots of filling to hide the weld joint lines! Cost me £3,500, but what a difference it makes to the car. I can supply photos if required, but notice you are down south and I am up near Harrogate.
