Benchlight hours

Where detail meets patience

Made for the task

Blotchy coats and uneven flow steal focus from the work. Scalecoat II Thinner 32oz Can—20505—keeps Scalecoat II model paints moving with a smooth, even spray and clean brush lines. It helps revive older bottles and supports fine detailing without breaking the rhythm. The result is consistent coverage that looks intentional, not accidental.

Finish that feels resolved

On a plastic shell or a delicate resin kit, surface tells the story. When paint levels cleanly, modeling reads as craft, not compromise. This thinner maintains the chemistry of the Scalecoat II system, so the finish looks durable and convincing. It lets the piece meet the eye the way you pictured it.

For the desk-bound perfectionist

Modelers using Scalecoat II paints who want predictable flow, fine detail control, and a professional finish across plastic and resin builds.

How it works at the bench

Start near a 3:1 paint-to-thinner ratio and adjust to your equipment and desired viscosity for airbrushing or hand-brushing.
