No. 2 Process Handgun Spray Techniques
TUBULAR WORK
The gun should normally be positioned about 4 to 6
inches from the part and held almost perpendicular
to the target surface. Spraying too close to the
part may cause runs and sags. Spraying too far
away from the part may cause overspray or allow
paint to wrap-back towards the gun.
Moving the gun in a straight line may not always
produce the most complete coverage or uniformity.
(See example "A".)
A slight waving or rotation of the gun can help
to spread the paint around the part better and
improve coverage. (See examples "B" and "C".)
> Small tubes (up to about 2-1/2 inches)
often may be coated by wrap-around from
one side. Larger parts are harder to wrap
completely from one side because paint
must miss target to wrap-around
Example: Not complete wrap-around, but
still good attraction and efficiency.
