It moves through The Professional Foundation, Mastering the Panel Line, Scribing and Surface Detail, Structural Modifications, Advanced Aesthetic Styles, Weathering and Damage, Tech and Integration, and The Master's Finish.

What you'll learn

Key ideas in Gunpla Customization and Detailing

  • Glass files use nano-etched surfaces to shave plastic rather than tearing it
  • Starting with 400-600 grit removes the bulk of the nub but leaves deep ruts
  • A glass file polishes the plastic to a high gloss while removing the nub
  • Glass file mechanics and finish
  • Progressing through 800 and 1000 grit gradually levels out previous scratches
  • Finishing with 1200+ grit ensures the surface is smooth enough for primer
  • Progressive sanding sequence
  • Safety nubs prevent breakage
  • Tack rags and anti-static brushes
  • Glass file polishing
  • Sharpening for scale accuracy
  • Rinsing plastic flour
  • Sanding grit progression
  • Lint prevention
  • Mold flash is a manufacturing artifact that creates an unwanted raised edge
  • Identifying the purpose of safety nubs on V-fins
