STAR S-770 Gravity Spray Gun

Star S-770 Gravity Spray Gun

The Star S-770 Gravity Spray Gun is a versatile gravity-fed spray gun designed for applying protective coatings, clear coats, primers, epoxies and general workshop finishes.

Featuring a stainless steel needle and nozzle assembly, adjustable fan control and a range of available fluid tip sizes, the S-770 delivers excellent atomisation, reliable material flow and professional-quality finishes across a wide range of coating applications.

The gravity-fed design provides a compact, self-contained alternative to larger pressure pot systems, making it an excellent choice for restoration projects, touch-up work, smaller coating jobs and workshop applications where mobility and convenience are important.

Recommended Endrust Coatings

The Star S-770 Gravity Spray Gun is particularly well suited to:

• Endrust PSXCLEAR 2K Clear Epoxy
• Endrust RXCLEAR Protective Coating
• Endrust RXBLACK Protective Coating
• Endrust UB702 High Build Epoxy
• Endrust RCP150 Rust Converter Primer Sealer

While larger coatings projects may benefit from a pressure pot system, the S-770 is ideal for smaller jobs, touch-ups, component coating and restoration work.

Why Choose a Gravity Feed Spray Gun?

Gravity feed spray guns use a top-mounted cup that allows coating material to flow naturally into the spray gun. This design improves material efficiency, reduces waste and provides excellent control when applying protective coatings and finishing products.

The compact design also improves visibility and manoeuvrability, making gravity guns particularly popular for restoration work, detailed applications and smaller coating projects.
