I too, have the same colour as your car. I had never used clay bar until today. Largely on seeing it come up, time and time again on this forum, decided to give it a go. I had never been completely happy with the finish I was getting on the paintwork with a range of different products. Now- total clay bar convert. So easy to use and so fast to get a great result.
One thing I have found with these cars is you really do need to want to do some of the work on them yourself. Otherwise, you will pay lots, often for, substandard work or service. Cleaning/ polishing and oil changing are inconvenient but at least you know it is done and done the way you want it to be.
