MG Nu Gundam Ver.Ka Weathering Guide | Decals, Chipping & Matte Finish

HOSS’S GUNPLA LAB • RX-93 • BUILD DETAIL 04

Decals & Weathering

The final finish adds panel lines, dense Ver.Ka markings, restrained wear and a matte clear coat without burying the gradation beneath.

The final finish adds panel lines, dense Ver.Ka markings, restrained wear and a matte clear coat without burying the gradation beneath.

Panel lining and the two-day decal stage

For panel lining I used black on the lighter areas and gray on the navy sections. This helped keep the lines visible without making every dark panel heavier.

The large number of decals took me about two days. I used decal softener to help a large marking conform to the curved calf armor. That detailed Ver.Ka look is rewarding, but it is definitely not a quick step.

Protect decals before handling the armor

When working on chipping I need to hold parts and touch their edges. Small decals can lift during that handling, so I sprayed a light matte clear coat to protect the markings before continuing.

Subtle chipping using a sponge

I thinned dark-gray enamel paint slightly with enamel thinner and touched it onto likely wear points with the corner of a melamine sponge. Testing the paint on tissue first helps avoid putting down too much color. Concentrating on edges and contact points was more convincing than covering every white panel evenly.

Gun Metal texture and shadow adjustment

A small amount of Tamiya Weathering Master C Gun Metal was rubbed onto selected dark-gray chips to introduce a hint of metallic wear. These powder accents can rub away easily, so gentle handling matters.

For the final shadow pass I used heavily thinned dark gray through the airbrush rather than my usual flat black. It produced a more natural effect on the white armor. This last shading step was for balancing the completed paint, decals and weathering, not repainting the base gradation.

Final matte coat and lessons from the build

After the chipping, Gun Metal accents and final shadows, I applied a matte top coat. The white areas held the weathering visibly, while marks on dark navy sections remained less obvious.

My main lesson was restraint. The armor already had shaded paint and detailed markings, so the weathering needed to support them instead of competing with them. More effects would not automatically have improved the finished model.
