IWATA WS Primer Professional Spray Gun for Filler Application (1.8 mm)

IWATA WS Primer Professional Spray Gun for Filler Application (1.8 mm)

The IWATA WS Primer is Anest Iwata’s first professional spray gun developed specifically for primer applications, optimized for filler application. It’s the perfect choice when OEM-quality finishes and a fast, efficient workflow with minimal post-processing are required.

The advanced Split Nozzle™ technology ensures precise and consistent atomization even at low pressure, while significantly reducing material consumption. The spray gun's ergonomic design and hard-anodized body provide comfort and durability even during intensive use.

Material Savings – More Efficient, Less Waste

Using the IWATA WS Primer not only improves the final surface quality, but also reduces material usage significantly. Thanks to its Split Nozzle™ technology, paint is applied exactly where it’s needed – with minimal waste and maximum efficiency.

Based on user experience, 30–40% material savings can be achieved compared to general-purpose spray guns, and even when compared to other professional tools, it still offers 10–15% more economical usage. This translates into cost-effective operation and faster return on investment for any body shop.
