Plan your Gundam Base Limited RG Sazabi Mechanical Core Clear build with clear-part handling, top coat choices, and display tips to keep the inner frame visible.

Quick answer

Treat the clear armor as the display feature, not a place to hide seams: assemble the inner frame cleanly, keep clear parts free of cement and fingerprints, and choose a top coat that protects without clouding the transparency.

Why clear armor changes your normal RG routine

On a standard RG Sazabi, armor hides most nub marks and frame imperfections. On the Mechanical Core Clear release, the clear plastic puts the inner frame on display, so every sanding scratch, stress mark, or stray fingerprint on the underside of a clear part becomes part of the look. Plan extra time for cleanup before assembly, not after.

The kit is a Gundam Base Limited release with a clear color scheme, so replacement clear runners may be harder to source than standard parts. That raises the cost of a mistake: test-fit before committing to glue or force, and keep clear runners separate from painted or sanded parts to avoid cross-contamination.

Top coat choices for clear plastic

A top coat can protect clear parts from handling scuffs, but the wrong product can turn transparency into frost. Use a clear gloss or clear semi-gloss designed for plastic models and apply thin, misted layers rather than a wet coat. Avoid matte coats on clear armor if you want to preserve the see-through effect; matte additives scatter light and can make clear parts look hazy.

Test on a clear runner first. Humidity and heavy coats are the usual causes of clouding, so spray in dry conditions and build up slowly. If you plan to pose the kit often, a gloss coat on the outer clear surfaces reduces handling marks; if the kit will sit in a case, you can skip coating the clear parts entirely and rely on careful handling.

Step-by-step build and display plan

Inventory and separate clear runners: Before cutting anything, check the clear runners against the manual and bag them separately from opaque parts. Common mistake: mixing clear and standard runners on the same work mat, which leads to lost or scratched clear pieces. Photograph the clear runner layout before assembly so you can identify parts later.
Clean nub marks on clear parts with progressive grits: Cut clear parts from the runner with a sharp nipper, leaving a small nub, then shave flush with a hobby knife and progress from 800 to 2000 grit wet sanding. Common mistake: skipping straight to a coarse file, which leaves deep scratches that no top coat will hide. Finish with a plastic polish on visible clear edges; test on a hidden area first.
Assemble the inner frame before adding clear armor: Build and clean the inner frame completely, then test-fit clear armor panels without forcing. Common mistake: trapping dust or shavings between the frame and clear armor, which becomes permanently visible. Use compressed air or a soft brush on the frame before closing each clear panel.
Keep cement away from clear plastic: Use cement only on opaque joints, and rely on snap-fit connections for clear parts. Common mistake: applying cement near clear edges, which causes fogging that cannot be polished out. If a clear part feels loose, check the manual for a locking tab before reaching for glue.
Apply a thin clear gloss coat if you handle the kit often: Mist a clear gloss or semi-gloss coat over the clear armor in thin layers, testing on a clear runner first. Common mistake: applying a wet coat in high humidity, which clouds the plastic. Let each layer cure fully before the next; stop at the first sign of haze.
Display with light from below or behind: Place the finished kit where light can pass through the clear armor, such as near a window or on a shelf with a small LED. Common mistake: backlighting with a hot bulb that can warp plastic over time. Use cool LED lighting and keep the kit out of direct sunlight to limit yellowing and heat.
