Quick answer
Start with roughly 1 part paint to 1–1.5 parts T-06 Leveling Thinner for airbrushing, then adjust by a few drops until the mix sprays smoothly and levels without pooling. For hand brushing, use less thinner and build thin coats.
Why a leveling thinner behaves differently from a plain thinner
A leveling thinner is formulated to help paint flow out and settle into a smoother film, so the same paint can behave differently than it does with a basic thinner. That is useful on Gunpla surfaces where brush marks or airbrush texture would show through a gloss or metallic coat.
The trade-off is that a mix that is too wet can pool in panel lines or soften underlying layers if you apply it heavily. Keep coats thin and let each one set before adding more.
When the starting ratio is not the right ratio
Humidity, paint age, and the needle size of your airbrush all change how a mix sprays. If the paint still looks grainy or dry at 1:1, add thinner a few drops at a time rather than jumping to a much wetter mix.
For hand brushing, a wetter mix can help leveling but also increases the risk of running into recesses. Test on a plastic spoon or an unused runner before committing to a visible part.
T-06 Leveling Thinner ratio FAQ
What is a good starting leveling thinner ratio for airbrushing?
Begin around 1 part paint to 1–1.5 parts thinner. Mix thoroughly, spray a test pass on a spoon or runner, and add thinner in small increments if the paint still spatters or dries before it levels. Keep a written note of the ratio that worked for each paint color.
Can I use T-06 to thin Mr. Color paint?
T-06 is a leveling thinner for model paints, so it can be used to thin Mr. Color paint for airbrush work. Because Mr. Color is a lacquer-based paint, test a small batch first and adjust the ratio to your airbrush and workspace ventilation.
How much should I thin paint for hand brushing?
Use less thinner than for airbrushing—start closer to 1 part paint to 0.5 part thinner and add thinner only if the paint drags. Apply several thin coats instead of one wet coat to reduce brush marks and pooling.
Is T-06 Leveling Thinner a lacquer thinner for airbrush use?
It is supplied as a leveling thinner for model paints, and it is intended for airbrush and brush work with those paints. Check the label and use it only with compatible model paints in a well-ventilated area.
How long does a 500ml bottle last?
A 500ml leveling thinner bottle is a practical supply for hobbyists working on Gundam model kits and other detailed projects. Actual longevity depends on how much paint you thin per session and how much you use for cleaning between colors.
What should I do if the paint still does not level?
Check the mix consistency first, then the air pressure and distance. A mix that is too thick tends to spray textured; one that is too thin can pool. Adjust one variable at a time and test on a runner before spraying the model.
