Elements and Performance Criteria updated to reflect mixing of paint products

Unit descriptor 

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.

Application of the unit 

Work applies to refinishing technicians in a repair environment and the application of clear over-base materials to a range of vehicles.

Work requires individuals to demonstrate judgement and problem-solving skills in managing own work activities and contributing to a productive team environment.

Employability skills 

This unit contains employability skills.

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge and/or the range statement. Assessment of performance is to be consistent with the evidence guide.
