Apply primers, base‑coat, top‑coat, and specialty coatings (e.g., anti‑static, conductive, thermal‑control) using spray guns, dip tanks, rollers, brushes, or robotic applicators in accordance with approved work instructions and coating data sheets. Inspect incoming parts and verify surface‑preparation specifications; perform cleaning, solvent wiping, sanding, abrasive blasting, or chemical strip‑off to achieve required surface roughness.
