Do I need paint or glue to build a Gunpla kit?

No. Bandai's snap-fit engineering and color-molded runners mean every kit in this roundup builds into a finished, recognizable model without paint or glue. Specialist-community builders on r/Gunpla note that panel-lining with a fine marker and a topcoat spray noticeably improves the finished look, but neither is required to enjoy the hobby.
