I didn't, no - or at least not personally.
I bought the calipers off a lad who was breaking his DB9 and then had them refurbished in that colour along with the rears. There's a bit of corrosion coming through on the rear calipers now though and I am torn between having them redone and changing the colour (and the front calipers) for something else.
I will have a look at the Labocosmetica stuff, thanks
