Elements and Performance Criteria

1. Prepare to mix and apply COB two-pack refinishing materials to vehicle body components
   • Job requirements are determined from workplace instructions
   • Vehicle paint specifications, technical data sheets (TDS) and paint safety data sheets (SDS) are accessed and interpreted
   • Refinishing materials are selected and inspected for quality
   • Hazards associated with the work are identified and risks are managed
   • Refinishing tools and equipment, including personal protective equipment (PPE), are selected and checked for serviceability
   • Work is planned to identify mixing and application methods for COB two-pack materials, minimise waste, prevent damage to vehicle, and use time efficiently
2. Mix COB two-pack refinishing materials
   • COB two-pack refinishing materials are calculated according to paint manufacturer specifications, formulas and codes
   • Codes and information relevant to job requirement are recorded
   • Materials are mixed according to workplace procedures and safety and environmental requirements, and without causing damage to components or systems
3. Apply COB two-pack refinishing materials
   • Refinishing materials are applied using manufacturer recommended method and intervals, and according to safety and environmental requirements
   • Refinishing materials are dried using approved methods and equipment to ensure painted surface meets specifications
4. Rectify paint faults
   • Paint faults are identified according to industry and workplace procedures
   • Rectification procedures are selected to suit fault or damage type
   • Materials to rectify paintwork are determined from paint manufacturer information
   • Paint surface faults are rectified using compounds, polishes and glazes to blend rectified areas with existing paintwork
5. Complete work processes
   • Final inspection is made to ensure work meets workplace expectations and component is presented ready for use
   • Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected and stored
   • Tools and equipment are checked, reported if faulty, and stored according to workplace procedures
