Thanks for the kind words, Saad...but to be honest, the entire air-brushing / flame-painting / custom paint design thing (which you've seen on the Impala) is ludicrously simple. All it really takes is some masking tape, some water-soluble markers, and a bit of imagination. Layering on the paint, and rubbing it smooth...is pretty much identical to how you'd paint any car. So really, brother...there's hardly any talent/vision/technique involved!
I think the more pertinent thing is that we (as vehicle owners) are unwilling to take "risks" with regards to our rides. We're wary of stepping beyond the circle of conformity, and experimenting with looks...and our technicians KNOW this, and even reinforce this. When I was flame-painting the Impala, I tried (unsuccessfully) to get a good job done with rattle-can spray paints, and decided that I needed some professional equipment. Well, the painter whose services I hired, immediately came out and said "bao ji, je kharab ho gaya, te mein idda zimmewaar koi naien" (if this thing ends up looking f***ed, I'm not to be held responsible). It was only after I assured him that I would do the painting myself, needed him only for his equipment and knowledge of how to use it, and was solely responsible for any inconsistencies, that he gave his assent to even work on the car!
I realise that fixing weird-looking, thoroughly botched-up design attempts is a costly and time-consuming process. But at the same time, nothing quite makes your ride so individualistic and unique as a one-off paint job. When we (as consumers) will make repeated demands upon our craftsmen and artisans for something of this sort, they'll learn all of the tricks of the trade and acquire all of the requisite hardware that are needed to provide us with the necessary solutions. Until then, we're going to have to admire (and envy) the custom paint, and flame designs, and airbrush art in magazines, I'm afraid!
