Quick answer
Apply AK11227 Penetrating Red over a cured gloss or satin clear coat. Use a fine brush to touch the ink into panel lines and recesses, let it capillary-flow for a few seconds, then wipe away excess with a clean, lint-free cloth barely dampened with enamel thinner. Work in small sections and avoid flooding flat surfaces, because this ink is designed for controlled flow, not full coverage.
Why use a penetrating ink instead of a standard wash
AK11227 Penetrating Red is part of AK Interactive's ink range, identified by the brown circle on the label. These are not standard acrylic washes. The formulation balances fluidity and intensity so the ink can travel through narrow panel lines and recesses while still leaving a strong red tone. That makes it useful for red panel lines, subtle color modulation on red or dark plastic, and weathering effects where you want the color to bite into details rather than sit on top. It comes in a 17ml bottle, which is enough for many small-scale projects if you apply it sparingly.
What you need before you start
Gather your kit parts, AK11227 Penetrating Red, a fine-point brush (size 0 or 00), a palette or small dish, enamel thinner or a compatible clean-up solvent, lint-free cloths or cotton swabs, and a clear coat (gloss or satin). You will also want good ventilation and nitrile gloves, because penetrating inks can stain skin and clothing. If you are working on a painted model, make sure the paint is fully cured before applying any ink. For bare plastic, a clear coat is still recommended to protect the plastic and help the ink flow evenly.
Step-by-step application process
1. Prepare the surface. Apply a thin, even coat of gloss or satin clear coat over the area you plan to treat. Let it cure completely. A glossy surface helps the ink flow into panel lines instead of soaking into the plastic or paint.
2. Shake the bottle well. AK11227 separates over time. Shake for at least 30 seconds, then let it sit for a minute to reduce bubbles.
3. Load a small amount of ink. Dip your brush tip only. You do not need a full brush load. Touch the brush to the panel line and let capillary action pull the ink along the groove. Work one line or one small recess at a time.
4. Let it flow, then wick away excess. After a few seconds, use a clean, dry cloth or swab to remove ink that has pooled outside the line. For tighter cleanup, barely dampen the cloth with enamel thinner and wipe perpendicular to the panel line. Do not scrub back and forth, which can pull ink out of the line.
5. Build intensity gradually. If you want a deeper red, apply a second pass after the first has dried. Thin layers give you more control than one heavy application.
6. Seal the work. Once you are happy with the effect, apply another clear coat to protect the ink and unify the finish. This is especially important if you plan to handle the model or apply additional weathering.
Common mistakes and how to avoid them
The biggest mistake is applying the ink too heavily. Flooding a panel line can cause the ink to bleed onto surrounding surfaces and leave a tide mark that is hard to remove without stripping the clear coat. Another frequent issue is skipping the clear coat. Without it, the ink can stain bare plastic or lift acrylic paint. Using too much thinner during cleanup can also dissolve the clear coat and ruin the surrounding finish. Finally, do not try to use AK11227 as a full-coverage red paint. It is a penetrating ink, not a base color, and it will look uneven over large flat areas.
Using AK11227 with other AK Interactive colors
If you are building a kit with multiple red tones, AK11227 Penetrating Red can be combined with other AK Interactive products for a cohesive look. For example, AK11175 Sky Blue is a standard acrylic color from the orange-dot range, designed for general painting. You can use Sky Blue for base coating and then apply Penetrating Red for panel lines or weathering, but keep in mind that the two products have different formulations. Always let the acrylic base dry completely before applying the ink, and test on a hidden area first. The 17ml bottle size is consistent across both ranges, so you can build a compact set of colors without committing to large volumes.
Application steps at a glance
- 1. Apply a clear coat: Seal the plastic or paint with a gloss or satin clear coat and let it cure fully. Checkpoint: the surface should feel smooth and dry, not tacky.
- 2. Shake and load the ink: Shake the bottle for 30 seconds, then dip only the tip of a fine brush into AK11227. Checkpoint: no large droplets hanging from the brush.
- 3. Touch into panel lines: Let capillary action pull the ink along the groove. Work one line at a time. Checkpoint: the ink should flow, not pool on flat surfaces.
- 4. Wipe excess carefully: Use a dry or barely damp lint-free cloth. Wipe perpendicular to the line, not along it. Checkpoint: no tide marks left on surrounding areas.
- 5. Build in thin layers: For deeper red, apply a second pass after the first dries completely. Checkpoint: stop before the ink looks glossy or uneven.
- 6. Seal the result: Apply a final clear coat to protect the ink and unify the finish. Next step: move on to decals or additional weathering.

The inks are not standard ones; the balance between fluidity and intensity allows challenging work, and the selection of tones is ideal for most possible tones. It comes in 17ml bottles. The brown circle helps you spot the ink range quickly on a crowded bench, and the fluidity means you can rely on capillary action for fine panel lines without thinning. The 17ml bottle is a practical size for detail work.
- AK11175 Sky Blue: AK11175 Sky Blue is from the basic range, marked with an orange dot. The clear label includes the color name and reference code at the top. It comes in 17ml bottles.
