With over 30 years experience in the North American composites industry, The Gelcoater knows what its customers need in a spray gun and backs them with the best warranty in the business!  The GX1000 gelcoat and resin spray gun, also know as the "dump gun" or "cup gun" is a perfect example of this.  

Designed and assembled in North America, this full size professional grade gravity feed spray gun quickly and easily sprays large amounts of gelcoat, resin, or any high viscosity material.  Its simple design allows for quick cup re-fills and cleans up in little time and with little solvent!  

The 5.4mm nozzle excels at spraying gelcoat, resin or any high viscosity material too thick for conventional spray guns.  The large nozzle and cup is perfect for quickly and accurately spraying large surfaces like molds, boats and hulls large and small as well as any composite refinishing job.    

With a large selection of nozzle tips, users can spray everything from automotive paint, clear coat and PVA to primer, metal flake gelcoat or undercoating.  The GX1000 can even be used to sandblast!

The GX1000 gelcoat spray gun comes standard with a free set of replacement o-rings (A $20 value!), a 5.4mm nozzle, aluminum spray gun lid, an owners manual featuring operation and care instructions for everyone from beginner to professional users, a 1000mL heavy duty polypropylene cup, a 32oz disposable paper cup liner and a squirt bottle for catalyst or cleanser dispensing.  

The GX1000 is constructed with higher quality materials than similar looking guns and is built with specially designed seals and materials to withstand acetone and other solvents used in the composites industry and has a better warranty than anyone in the business!
