A panel lining marker helps bring out the detail in a Gunpla kit. Gundam models have lots of grooves, armour lines and mechanical shapes. Without panel lining, some of that detail can look flat, especially on plain plastic.
Panel lining is one of the easiest ways to improve a kit. You simply add a thin line into the recessed details, then clean away any extra ink. The result is a sharper model with more depth.
Different colours create different effects. Black gives a strong, bold look. Grey is softer and works well on white armour. Brown can look natural on warm colours such as red, yellow or tan. Choosing the right colour helps the lines look cleaner and less heavy.
You do not need to paint the whole kit to enjoy panel lining. That is why it is such a popular first finishing step for beginners. It is quick, affordable and makes a visible difference.
Panel lining also pairs well with decals and top coat if you want to keep improving your builds. Kidultverse stocks panel lining markers and finishing tools for Gunpla builders who want their kits to look cleaner, sharper and more detailed.
