Which of these procedures would help find pits, blisters in

A. Blowing and dusting the repaired area
B. Wire brushing and dusting the repaired area
C. Block sanding the area with a medium-grit paper
D. wiping off the repaired area with thinner - Answer-The

Painter A says that if one of the air holes labeled 'A' is

D. Neither A or B - Answer-The correct answer is a. The
holes emit A stream of air that defines the shape of the

pattern, the deformation in the illustration is caused by
clogging of air holes

A. Too much drying time in between coats
B. using too high an air pressure
C. Wrong temperature reducer
D. Improper overlap with spray pattern - Answer-The
correct answer is D. The pattern liked the overlap

B. Painter B only
C. Both A and B
D. Neither A or B - Answer-The correct answer is a period
allowing flash time between coats gives the solvent in the
paint a chance to escape from each application, resulting
in a faster overall dry time and no risk of trapping solvents
under several heavy coats in sequence. Also, if paint is
allowed flash time between coats, the material will tend
not to run out of surface scratches.
The door shown above has a large number of paint chips,
but no dents. The paint is the original finish. Painter A says
that the chips could be filled with an application of
polyester glazing putty before refinishing. Painter B says
that the chips should be sanded out before refinishing.
