Application
This unit describes the performance outcomes required to mix and apply clear over base (COB) paint materials to vehicle body components. It involves preparing for the task, selecting and using specialist tools and equipment, identifying paint faults, preparing surface to be painted, selecting and applying COB two-pack refinishing materials according to manufacturer specifications, and completing workplace processes and documentation.
It applies to those working in the automotive paint refinishing repair industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of task.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the COB two-pack materials they have applied to vehicle body components, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
paint and vehicle manufacturer specifications and paint codes
TDS and SDS for COB two-pack paint
PPE, including positive air feed masks
COB refinishing materials
three different vehicles with body components specified in the performance evidence requiring painting with COB two-pack refinishing materials
tools, equipment and materials appropriate for applying COB two-pack refinishing materials.
