Description
This unit describes the performance outcomes required to mix and apply clear over-base refinishing materials in two-component systems to a variety of vehicle bodies and substrates by spray-gun application. The unit involves determining causes of paint finish faults and suitable rectification procedures. The unit also involves preparing for work and completing work finalisation processes, including clean-up and workplace documentation.Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.
