1.6 MM is the suitable nozzle size for primer coat
Normally, each nozzle size provide a different spraying feature, 1.3 mm for base coat, 1.4 mm for clear coat and 1.6 mm for primer coat. Therefore the spray gun that we present it for you is the alternative choice for customer who find the specific spray gun for primer coat progress. The nozzle size 1.6 mm may not be available for other coating type. The similar case is the water based clear coat.
The primer coat spray gun is the same series and model of spray gun for base and clear coat. There have both size cup and center cup which is depended on the sprayer. KIWAMI1 B-SHO is the lowest price of automotive refinishing spray gun but the performance is sufficient of primer coat already. The other model have a higher performance but it will be the optional item for consideration.

KIWAMI1-16B2 (B-SHO) spray gun for primer coat only
KIWAMI1 B-SHO or KIWAMI1BH is the selected item for primer coat only with nozzle size and the price is cheapest when compare with other automotive refinishing spray gun model. Even the the price is higher than the WIDER1G series in a few amount but the different price is offset by the performance of primer coat is better and sufficient for this application. You can use with other spray gun model for base and clear coat without problem.
Reason to choose KIWAMI1-16B2 (B-SHO)
-
For sprayer who require the spray gun that it is created for primer coat application only. Even the WIDER1G with nozzle size 1.5 mm can be sprayed for primer coat but the performance still lower than specific primer coat spray gun because the air cap of primer coat spray gun can make a better spray pattern and has 1.6 mm which provide more paint flow rate.
-
When compare with KIWAMI1RT or center cup spray gun model KIWAMI4, KIWAMI1-16B2 price is lowest so it is a good optional item for consideration of selecting primer coat spray gun.

KIWAMI1-16B12 (RT) the optional item for high viscosity paint.
KIWAMI1RT with nozzle size 1.6 mm is the optional item for primer coat when the material is extremely high viscosity or water-based. If you use KIWAMI1BH, you may find it that the spare part will be depreciable more than usual because the nozzle is depreciated quickly. This is the special model for sprayer who consider it as the optional item because they need a spray gun which can spray both normal paint and high viscosity paint and the spare part is robust than normal model. The price is higher than KIWAMI1BH but still lower than KIWAMI4.
Reason to choose KIWAMI1-16B12 (RT)
-
For sprayer who require the robust spray gun in order to apply with high viscosity paint but still need side gravity cup model.
Component of KIWAMI1-16B2 (B-Sho) and KIWAMI1-16B12 (RT)
A. Aircap Create the spray pattern to make atomization in order to coat the surface.
B. Nozzle The outlet of paint flow that it is covered by aircap.
C. Gravity Side Cup Connector For KIWAMI1, the side cup 400 ml connector is located of beside nozzle and male connector is G1/4.
D. Needle Packing It's located near fluid needle which is open/close paint flow in order to protect the fluid leakage.
E. Trigger Newly-design for ergonomic handle.
F. Spray Pattern Adjusting Knob Enable to adjust to be wide or narrow but it's depend on spraying distance between workpiece and nozzle.
G. Paint Capacity Adjusting Knob Enable to increase or decrease paint flow. Normally before start to work, you may set the default value by adjust knob follow the clockwise reach to maximum level then adjust know counter clockwise 3 round and half (use the line marker on knob as round counting).
H. Handle Newly-design which make be more comfortable of handle.
I. Air Adjusting Knob Increase or decrease air flow. However, many of customer use additional air pressure regulator and gauge with spray gun so this knob is demoted to be open fully the air flow. The air pressure adjustment is belong to additional air pressure regulator.
J. Air Connector The connector size is G1/4. Normally, it is regular to connect with additional air pressure regulator and gauge. Therefore, the air hose is connected with air pressure regulator instead connect directly with spray gun.

KIWAMI4-16BA4 the center gravity cup spray gun for primer coat
KIWAMI4BA is the center cup for base coat and clear coat but this model provide the 1.6 mm nozzle that it is available for primer coat and also use for water-based clear coat.
Reason to choose KIWAMI4-16BA4 for primer coat
-
It is possible that the 1.6 mm model is sold by nozzle needle set spare part rather than full spray gun because the primary work is base and clear coat. It is suitable when you have only 1 spray gun. but need to buy additional nozzle needle set for changing part following the application. Actually in case of separating spray gun for each application, the primer coat is possible to be side gravity cup.

KIWAMI4-V16WB2 the center gravity cup for primer coat
The water-based model and primary application of 1.6 mm is the clear coat with water-based paint because the higher in viscosity and droplet is larger. That's why 1.6 mm is required but this size is suitable for primer coat which is the standard practicable for primer coat spraying.
Reason to choose KIWAMI4-16WB2 for primer coat
-
It is low possible to choose this model for primer coat because the price is most expensive and the main purpose is base coat and clear coat. Mostly, the primer coat is selected to choose with side cup spray gun.
-
It might have a reason that the regulation of painting application in each area require this spray gun model in order to perform the spraying work in order to achieve the standard regulation and determination of material paint and spray gun.
Component of KIWAMI4WB and KIWAMI4BA
A. Aircap Create the spray pattern to make atomization in order to coat the surface.
B. Nozzle The outlet of paint flow that it is covered by aircap.
C. Center Gravity Cup Connector For KIWAMI4, the center gravity cup is PC-G600P-2 with 600 ml capacity and male connector is G1/4.
D. Needle Packing It's located near fluid needle which is open/close paint flow in order to protect the fluid leakage.
E. Trigger Newly-design for ergonomic handle.

G. Paint Capacity Adjusting Knob Enable to increase or decrease paint flow. Normally before start to work, you may set the default value by adjust knob follow the clockwise reach to maximum level then adjust know counter clockwise 3 round and half (use the line marker on knob as round counting).
H. Handle Newly-design that the overall of spray gun is shorter than W-400 3.5 mm but the handle grip is longer than 5 mm which make be more comfortable of handle.
I. Air Adjusting Knob Increase or decrease air flow. However, many of customer use additional air pressure regulator and gauge with spray gun so this knob is demoted to be open fully the air flow. The air pressure adjustment is belong to additional air pressure regulator.
J. Air Connector The connector size is G1/4. Normally, it is regular to connect with additional air pressure regulator and gauge. Therefore, the air hose is connected with air pressure regulator instead connect directly with spray gun.
