Message from developer of Project KIWAMI

KIWAMI Developer Pic.png

Our development of new models is driven by the way we care for our customers and for our products.

The key point when we create new models is “taking the customer’s point of view”, which is Anest Iwata’s management philosophy. At Anest Iwata, the people in charge of our marketing are former technical painters who have actually painted in real world applications. When they

visit customers, they identify issues and then address them in product development proposals that take the customer’s point of view into consideration.


Our work on the development team is to create new spray guns that embody these customer needs. In designing these new products, our development team went through many iterations of prototype fabrication and trials, tuning the product in many ways to deliver maximum painting performance.


The “New ‘kiwami” was finally completed by passing our stringent quality control standards. Throughout the process, our team was driven by the desire to deliver the

most advanced and highest performing products to our customers.

We wanted our design to honor our heritage but also highlight the evolution or our newest technologies.

The key concepts in our development of the “New ‘kiwami” series was that it should “Honor our heritage” and use “evolving technology.” We started our development work with the challenge of “making spray guns that embody two apparently contradictory concepts.” To put it another

way, we had to put ourselves in the shoes of our customers who have always loved using our existing designs. Then, we had to adapt to the considerable advances in coatings, adding the latest atomization technology.


It was our mission to achieve these two things. There has been a trend lately for consumer automobiles to come standard with very deep and beautiful colors. These can be a challenge to apply. There is a need for spray guns for such coatings that would

make application simple. Such coatings will likely continue to become more common. 

We will identify such trends in tastes regarding colors and go on strengthening our ties with paint manufacturers in order to produce ideal spray guns. We will also make efforts to improve quality to satisfy the needs of our customers.

Perhaps what we’re really looking for as spray gun developers is for our customers to say “I can only paint with Anest Iwata spray guns.”

Overview of automotive refinishing spray gun according to intention of KIWAMI


Behind every finishing by giving the extremely best item

ANEST IWATA Spray gun which is  sold by R.O.M. Intertrade will be the KIWAMI model as the primary product because this model is developed the quality and performance higher than previous model. It is available for every sprayer that the performance is usable both solvent-based and water-based and also provide the special model for water-based as the optional item.


In order to let applicator consider the most suitable product for themselves, the presentation will be separated by application type following as below;

The first 3 groups are primer coat, case coat and clear coat. It is possible that you will find the same spray gun in every group because the standard primary model provide the nozzle size which is available for 1.3 mm - 1.6 mm. The general practice for nozzle selection are following as below;

  • 1.3 mm nozzle Size is the general practice for base coat. The meaning that base color is the actual identification of surface color and special color such as metallic, pearl and other color which are base coat. Generally, the base coat does not need to spray the too much volume of paint. The 1.3 mm nozzle size is regular size for base coat that it can control the thickness to prevent the color is slipped out from surface. By the way, some coating does not require 1.3 mm for base coat. 1.4 mm can spray the base coat if the paint is high viscosity or water-based paint.

  • 1.4 mm nozzle Size is a general practice of clear coat which make a base coat color on surface to be clarity and making reflection. It is the final phase of coating. According the objective of clear coat, the nozzle require to be larger than base coat which can provide more sufficient paint quantities to make the reflection with full performance. Actually, some applicator use 1.3 mm for clear coat but the paint volume is less so the reflection might not be the same as 1.4 mm.

  • 1.6 mm nozzle size Actually, this nozzle is not a regular practice for primer coat same as base coat and clear coat because many of paint applicator use 1.5 mm nozzle from general industry spray to spray primer coat. In other hand, the 1.6 mm nozzle size is the best size for primer coat because the objective intend to make adjusting the surface status and make adhesion force before spray a base coat. The colorful quantity is not required but the equally thickness level on surface might make a better adhesion force for longer life time.

The spray gun for base coat and clear coat will be the same categories with 3 different types but the primer coat is separated to present in other categories because R.O.M. select the spray gun model "KIWAMI1 B-Sho" with 1.6 mm for primary primer coat spray gun. The other model with 1.6 mm nozzle size is the alternative choice for consideration.

Primer Coat Application Spray Gun

Objective of Primer Coat

The spraying application for adjusting and preparation of surface in order to make adhesion force before base coat phase. The material paint can protect the surface body to prevent the rust and corrosion in long term so the viscosity might be high and require the large volume of paint. The regular nozzle size is 1.6 mm.


Base Coat and Clear Coat Application Spray Gun

Objective of Base Coat
