#1: Clogged spray gun resulting to vertical blanks, gun too close; paint might drip. #2: Spray gun shouldn't swing with the arm which results to poor coating in both sides and heavy coating in the center; paint might drip #3: Spray gun way too close, nozzle spread too narrow, poor coverage #4 Coverage is good enough but still need improvements, spray gun is a bit too close #5 Pressure too high, paint can't flow properly into the nozzle. Guy is better suited as shipyard painter judging from his spray gun movements. #6 Pressure too high, paint can't flow properly into the nozzle, spray gun too close. #7 Same as #5 #8 Guy knows his thing, good posture, even coverage. Highly recommended. #9 The way he swings the gun in the 1st coat is fine but is a bit too fast. He sprays the gun like a rattle can after the 1st coverage; spray gun clogged #10 Spray gun too close, nozzle too narrow; poor range of motion #11 Same as #10 #12 Again, same as #10, spray gun should glide over not swing.
