Stop Rushing Your First MG. I Did, and I Regret Every Shortcut.

My first MG was the Freedom Gundam. I bought it the same day I finished my third HG, convinced I was ready. Two evenings later I had a completed kit with three stress-marked panels, two slightly misaligned armor pieces, and a torso that clicked when I moved it because I'd forced the inner frame joint in the wrong direction.

It still sits on my shelf. I don't like looking at it.

The Inner Frame Demands Your Attention

HG kits are forgiving. You misread a step, you take it apart, you fix it. MG inner frames are not that forgiving. Forcing a joint in the wrong direction can stress or even crack the polycap housing — and once that happens, that joint is looser forever. Read the manual step. Complete that step. Only then move on.

I know this sounds obvious. I also know that the excitement of building something new makes you want to skip ahead. Resist it.

Don't Force Anything

If a part doesn't go in easily, don't push harder — look closer. MG parts have orientation markings for a reason. A round peg might have a small flat side that needs to align with a matching flat channel. A frame piece might only seat correctly from one specific angle. If something isn't clicking in with gentle pressure, you have the wrong part or the wrong orientation. Never the wrong force.

Build the Inner Frame First. Admire It.

Seriously. Build the full inner frame, set it aside, and just look at it for a few minutes. Pose it. Appreciate it. This is the foundation of everything and it deserves respect. When you rush through the inner frame to get to the armor, you miss the entire point of Master Grade engineering — and you're more likely to make mistakes you'll notice later.

My Second MG

MG Nu Gundam Ver.Ka. I took five evenings. I used nippers properly. I checked every step. I built the inner frame, posed it, took photos of it before the armor went on. The finished kit is one of my favorite things I own. Same price range, completely different experience. Slow down.

The MG Build Tutorial: What Veterans Don't Mention

MGs are different from HGs. The build is longer. The articulation is deeper. The detail is finer. But the techniques transfer — every MG you build improves your HG builds, and vice versa.

The Multi-Evening Approach

Don't try to build an MG in one sitting. The build is naturally divided into phases: inner frame, outer armor, weapons, decal/finish. Each phase is a satisfying milestone. Plan 2-3 evenings for a typical MG build.

Speed-building leads to mistakes. Mistakes lead to frustration. Frustration leads to abandoned kits. Pace yourself.

The Inner Frame First

MGs build from the inside out — inner frame first, then armor over it. This means your kit looks 'incomplete' for the first 30-40% of the build. That's normal. Don't try to add armor early.

The inner frame phase teaches you the kit's joint architecture. Pose the frame as you build it; you'll understand the kit's articulation behavior before committing to armor.

The Decal Application

Most MGs include comprehensive decal sheets. Apply them per the manual; they significantly elevate the kit's visual richness. Skipping decals is the single biggest reason MGs look 'unfinished' on display.

Allocate 1-2 hours for decal application per MG. Use the technique covered in the waterslide decals tutorial for best results.

The Top Coat Decision

Most builders skip top coating MGs. They shouldn't. A semi-gloss top coat unifies the visual finish, seals decals, and protects the kit during shelf display. Cost: ~¥600 for a can; covers 5-8 MGs.

Apply two thin coats. The result is dramatic — the kit transforms from 'painted plastic' to 'finished display piece.'

The Aftermarket Upgrades

Bandai's 'Builders Parts HD MS Hand' upgrade gives older MGs better hands. Aftermarket decal sheets (Mecha Skunk Works, Samuel Decal) provide unit-specific markings beyond stock kits. Action bases (Bandai Action Base 5) support flight-pose display.

None are essential. All elevate the build experience.
