I've made progress on painting the finer details.
I'm adding lines and other details to each part using a brush.
Even though I'm using a brush to paint the lines, I'm hesitant to draw them freehand right away, so I'm using masking tape to create guides. I used Tamiya enamel red.
I corrected any mistakes, such as warping, with a cotton swab soaked in enamel thinner.
Next, I prepared the decals that came with the Sleggar's GM that I didn't use before.

I started building the Best Mecha Zaku (Part 7) | ヘイカユウジ's Gunpla works
