Repaint - which paint brand ???

I am going to repaint my car with my original color Rosso Corsa. I just putted complete CS kit which means i have to paint practically 1/3 of the car. Rest of the car (doors,hood.....) have some scratches,dents... so i decided to make full repaint. I will avoid possible difference between new/old paint + i will have brand new paint without scratches.

Ferrari use PPG paint. But my paintshop use Standox paint. They told me that PPG and Standox is practically produced by one producer and there is only marketing issue behind that and fact that PPG and Standox buy from same producer. They say that hey will get Rosso Corsa from Standox and there will be no difference at all compare PPG. Its one of the best paintshops so i trust them. However i am curious if you know the brand of paint which was used for your cars in case you repainted bumpers, etc.... Can you post your experience? Did you use PPG or other brand?
