Well, whereas the paint job is concerned, I would want to be gracious to avoid any desi 'jugaarr' because following exactly is the finish I would want after spending money:

You could be right and satisfied with above suggested way too, I so respect you for stepping up to help me out, bro! But to tell the truth, most paint mixer guys make for you 'almost that' color for your car. Human error is not to be ignored, even a quarter teaspoon excess of thinner can ruin the entire shade, and then, the painter would say; "oh sir jee same hi hai, abhi dhuup hai, is liye shade aa raha hai, abhi chhaao'n hai, abhi angular..." and the crap goes on! Javed & Baau at Lahore, of course are exceptions, totally out of this world, no doubt but even they ask you to bring the paint along! I do not allow this fraudulent sector of 'skilled' auto-guys cheat me on cost of my hard-earned money, let alone me, no body would, right? That's only why I would want to go for the entire formula- with a perfectionist approach- as per the manufacturer. We, of course, would need to know the base coating & colors as well as the quality and quantity finishing lacquer.
So, as I myself take the finishing jobs seriously and for I have spent almost a million PKR on a 1973 classy JDM coupé, I just wanted to bother a bit more just to achieve my point of satisfaction with a little homework prior to action plans.
Please do not feel offended in anyway for this my friend, would never be my intention. Above is just, my point of view. And for I live in my body and inside my stubborn brain, I have to take the route to my own point of satisfaction, idiotically:D
