What this video covers
This video is the concluding chapter of a three-part Ghostbusters Proton Pack build series, focusing entirely on weathering and finishing a 3D-printed replica into a screen-accurate prop. The creator walks through multiple weathering techniques including rub and buff, paint washes, and Fuller's Earth to achieve a grimy, battle-worn aesthetic. Additional upgrades covered include swapping in a period-correct Neutrona wand and integrating a custom smoke effects unit. The build culminates in a reveal moment featuring a real Ghostbusters cast member's reaction.
