    But a funny thing happened fairly recently: we got more critical. Dissatisfied with good enough, we now strive for greatness. Now, flawless paint isnt just reserved for show cars weve come to expect perfection for our drivers.

    Typically speaking, most paint stories emphasize the importance of preparation. And its true what you see relates directly to what happened before the paint went on. But the finishing process doesnt end once the clear goes on. In fact, to some, like our pal Jason Killmer, cured paint is just a blank canvas.

    Jasons a detailer, but not the kind who cleans cars. Hes the guy who perfects seemingly impeccable parts that make up mind-blowing show cars. And buildersthe biggest names in the industryfly him all over the country to do it. He doesnt just make cars prettier, he make them winners. He has multiple Don Ridler Memorial Awards under his belt.

    Make no mistake that theres still a big gap between an inexpensive production paintjob and a full custom job. But the vast majority of enthusiastsmaybe even youcant spot the difference after a little bit of work.
