TUBA ECONOMY SPRAY GUN 1.8

Laying down a flawless finish starts with a perfect foundation, and our TUBA Economy Spray Gun 1.8 is the ideal tool for the heavy lifting. While your 1.4mm gun handles the final color and clear coat, this highly affordable, dedicated primer gun is specifically engineered to push thick, heavy-viscosity materials that would choke a standard spray gun.

Equipped with a large 1.8mm fluid nozzle, this gun delivers exceptional atomization for thick 2K high-build primers, primer surfacers, heavy sealers, and sprayable polyester putties. It lays down an incredibly smooth, heavy coat of primer with an even fan pattern, reducing your block sanding time and providing the ultimate laser-straight foundation before you apply your final Custom Creative Base Color Solid.

Designed with a lightweight, ergonomic aluminum body, it reduces wrist fatigue during full, all-over vehicle priming. By keeping this economical workhorse as your dedicated shop primer gun, you prevent heavy, fast-curing primers from ruining the delicate internal components of your expensive basecoat and clearcoat guns.
