We are pleased to announce the release of the successor model to the highly acclaimed spray guns "FINER" and "FINER2." What is the essence required for a spray gun specifically designed for automotive repair? We have returned to this fundamental question and thoroughly re-evaluated all the know-how accumulated since the development of the first domestic model from scratch. By listening to the voices of skilled painters, we pursued particle control and achieved ideal spray characteristics with excellent flow control technology. The refined craftsmanship shines even brighter when accompanied by polished tools. Developed as a tool that responds to the skills and sensibilities backed by this technology, the "Master Craftsman Project" introduces the evolved "F-ZERO" series in three types. Additionally, we are launching the first metal cup with a packless one-touch lock, the "4GF-U" gravity feed paint cup, which overcomes the issues of previous models and further enhances workability. This will be released as a limited initial production pack at a commemorative price, alongside the new F-ZERO launch.
