There are many metallic effects (eg google brushed aluminium). But here is a simple one that may suit your needs.

1) Select the gray with Fuzzy Select tool, threshold 40. Use the Mode "Add to current selection" to get the different parts.

2) Use Filters > Noise > RGB Noise with a setting of 0.20 (Or 0.10 if effect is too strong)
