The guy looks to be a very good painter. I would guess the temperature is not very high, or the air very dry. If I tried that where I live, the paint would be dry, for the most part. His first coat, just getting a good tack cover. If I tried to paint like he does, with the gun that close, I would be screwing up with runs, I have to pull away a little bit more, I am not that experienced. His second, the gun pulls away about approx. 8-10 inches, he's not getting striping and he is going opposite of his first coat, not sideways but up and down the second coat. The third coat, what I call a fog coat, the gun is approx. 12 -16 inches away, he's blending and will avoid getting the "tiger stripes". The clear coat, he's just laying it on to avoid runs, that bumper would be a bear to paint for a beginner, lots of flat places going into contours. I would bet this guy paints a mean motorcycle. This is where I would have a problem with getting it too dry or getting a run, especially in the summer, hot and dry weather. It's interesting to see how he blends into the door, kind of a sweep that lays on just a very light coat. If this was a complete job, you would want to avoid that. Cool video, thanks for posting. We have a few much more experienced painters here, I would like to hear their opinion on this guy also.
