The painter I use does work on top end cars and is a Ford man as well. He has done work on many RS 500s etc where the customers wanted a flawless finish.
I explained to him what I wanted and due to his skill, not luck, he delivered. He will be doing the side skirts and some bonnet touching in for me soon and I am not worried at all that it won't be as good as his previous work.
Good skilled painters are thin on the ground but they are out there and once you find one you will use him all the time.
I thing I learnt was how many different shades of diamond white there are, I just assumed it was one but that is not the case. Colour matching is where the painters skill is so important, 23 years of polishing alters the colour as well!!
