The standard, stock hopper that comes with your gravity feed spray gun works — but it has some limitations:

• It lacks a built in filter, and requires you to pre-filter paint as it is poured into the hopper.
• You must keep the gun upright at all times, so gravity can feed the paint into the gun.
• Cleaning after use requires a full teardown; which requires significant time and lacquer thinner.

The Spectrum Universal Paint System (UPS) can be purchased at your local Harbor Freight store. It provides many advantages over the stock hopper:

• The UPS incorporates a screen built-in to the lid which filters the paint as you spray — eliminating the need for messy pre-filtering.
• Paint is held in a flexible, vacuum-sealed inner liner. As you spray, the liner collapses to ensure a continuous flow of paint, even when the gun is held upside-down. This gives you freedom to position the gun at any angle necessary to get complete paint coverage on your work piece.
• The inner liner is disposable; which greatly reduces the amount of time and lacquer thinner needed to clean the spray gun.
• It allows for quick and easy color swapping when using multiple colors of topcoat.

The Sagola Disposable Paint Cup (DPC) system can be purchased directly from Spectra Chrome; and offers all the same advantages over the stock hopper as the Universal Paint System (UPS) from Harbor Freight. However, the Sagola DPC system comes in a smaller 7 oz. size — which is better suited for the LI System’s smaller typical spray volumes.
