I had a hit and run on my ed30 and the body shop pulled of a blinder, you cant tell its had two doors painted I was well chuffed.
What you need to take into account when getting bits sprayed is
1 - the year of your car, if the car is 2 year old the paint will have weathered somewhat in that time, so fresh paint will differ
2- factory paints will differ from body shops as they maybe the same paint code but the ingredients maybe from differnet suppliers.taking into account inferior paint costs etc..
a classic case of this is the MKII Leon FR/cupra (any mode)l, a brand new car but look closely espec the silver & red versions and you will notice a slight difference. Its more noticeable under a camera flash it really stands out.Seat advised this is due to the body work being sprayed in one country and the bumpers another, same paint code diff supplier of ingredients.
