Oil washes and filters have one recurring side effect: satin sheen where you wanted a flat, realistic finish. Abteilung 502's Matt Effect Thinner (ABT112) solves it at the source — it's their ultra-smooth thinner with a matting agent built into the formula, so your washes, filters and oil effects dry matte from the off, no varnish rescue required.
Best for
- Matte washes and filters over flat military and monster paintwork
- Any oil work where a dead-flat finish is the whole point
- Combining with any oil or enamel paint already in your collection
One thing worth knowing: the matting agent can settle into visible particles in the tin. A good shake dissolves them and you're away.
