Well, Paint technologies are improving...but it only helps the companies to reduce costs of production and pollution rates due to VOC's.
Nevertheless...the Paint is way more delicate...and this is because the 3 layers (Primer,Base and Clearcoat) are bonded in wet. If you scratch your car, you'll see a brown layer...thats the E-Coat. In the conventional process, Base is aplied after a cured primer.
An expert will say you are getting the same quality (resistance, paint thickness,appareance), and data can prove it ...but even so...paint comes out way to easy!
...good old paint U_U
