Application
This unit describes the performance outcomes required to carry out final polishing activities on vehicle painted surfaces. It involves preparing for the task, selecting and using specialist tools and equipment, identifying paint defects, selecting buffing and polishing materials, de-nibbing, buffing and polishing surfaces, 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.
Elements and Performance Criteria
Elements Elements describe the essential outcomes. | Performance Criteria Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section. |
1. Prepare to carry out de-nibbing, buffing and polishing | 1.1 Job requirements are determined from workplace instructions 1.2 Surface repair and finish materials are selected and inspected for quality 1.3 Hazards associated with the work are identified and risks are managed 1.4 Hand and power tools, including personal protective equipment (PPE), are selected and checked for serviceability 1.5 Work is planned to identify methods for de-nibbing, buffing and polishing, minimise waste, and prevent damage to vehicle |
2. Carry out de-nib, buff and polish activities | 2.1 Paint contaminants are identified and removed using paint cleaning clay bars 2.2 De-nibbing is conducted to remove minor paint inclusions and paint defects 2.3 Hand and machine buffing and polishing are conducted according to workplace procedures and safety and environmental requirements |
3. Complete work processes | 3.1 Final inspection is made to ensure work meets workplace expectations and vehicle is presented ready for use 3.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected and stored 3.3 Tools and equipment are checked, reported if faulty, and stored according to workplace procedures 3.4 Workplace documentation is processed according to workplace procedures |
Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in this unit’s elements, performance criteria, range of conditions and foundation skills:
de-nib, hand and machine buff, and polish the painted surfaces of three different vehicles.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to de-nibbing, buffing and polishing vehicle painted surfaces, including procedures for:
selecting and using personal protective equipment (PPE)
handling and storing polishing materials
using tools and equipment
environmental requirements, including procedures for trapping, storing and disposing of waste materials
techniques for buffing, polishing and de-nibbing painted surfaces, including:
use of paint cleaning clay bars
use of de-nibbing and polishing materials
methods to reproduce original equipment manufacturer (OEM) and adjacent panel surface finish to pre-refinished condition
effect of silicones and silicone type polishes on refinishing quality
paint faults and rectification procedures
types and correct use of de-nibbing, buffing and polishing equipment
procedures for protecting vehicle and components when de-nibbing, buffing and polishing vehicle painted surfaces
procedures for final inspection of de-nibbed, buffed and polished vehicle painted surfaces.
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 vehicle painted surfaces that they have de-nibbed, buffed and polished, e.g. work 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
PPE required to buff, polish and de-nib painted surfaces
materials required to de-nib, buff and polish vehicle painted surfaces
three different painted vehicles requiring de-nibbing, buffing and polishing
tools, equipment and materials appropriate for de-nibbing, buffing and polishing vehicle painted surfaces.
