Test fit each parts before gluing together. You may need to clean the pieces by putting of medium grade sandpaper (40/60 grade), also you may need to fill some air bubble. When you are happy with the fit of each parts, you can start to paint them, use a primer so you can easily detect other small imperfection, when you are satisfied of the primered surface, paint all resin parts with semi flat black color. Paint the grips with Ivory color, paint in silver or alluminium the circular resin tube the goes place inside to emulate the barrel.Use the 5-minutes epoxy glue to join the resin parts.Shine the metal parts for give alluminium surface appearance, use a very fine sand paper for precleaning the metal , then with dremmel tool, use a brass brush, at lowest dremmel speed shine the surface very gently, you can use super glue to fix them.Grips doesn't need of glue they must fixed with four screws (included).
