I had mine done by Paintshield who are by Corby. I had previously had the do my Porsche and for what it costs is a no brainer.
They do 3 packages from memory, a Half Front kit which is front bumper, bonnet only up to half way and wing mirrors, a full front package which is bumper, all the bonnet and wing mirrors or they do the whole car.
I had the full front package but also had the sills done too and it cost about £1k. My car is now 2 years old without a blemish.
Give them a call for a quick price
