Cert III Refinishing · Work through your exam, one topic at a time.
AUR32420 Certificate III in Automotive Refinishing Technology is an Australian qualification for people who paint, refinish, repair and maintain painted surfaces on automotive vehicles, recreational vehicles and other vehicles in the automotive industry. It suits apprentices and trainee refinishers building a trade-level career, and experienced spray painters seeking formal recognition of skills such as substrate preparation, priming, colour matching and clear over base application. The qualification is packaged as 30 units: 18 core units plus 12 elective units. All 12 electives may come from the listed elective units, and up to 5 units may be drawn from a Certificate II qualification or above in this Training Package or another endorsed Training Package or accredited course. Topics on this exam: Core units and Elective units. The Cert III Refinishing study guide has 2 sections and about 864 words.
01Core Units: Safe Practice, Surface Preparation and Coatings Fundamentals
Core units establish the non-negotiable foundation of automotive refinishing: work health and safety, workplace communication and documentation, environmental and waste obligations, surface preparation, masking, colour matching, and application of undercoats and topcoats. Questions test whether you understand why a step exists, not just the order of steps. Hazard control hierarchy : elimination, substitution, engineering controls (spray booth extraction, ventilation), administrative controls (SDS, training, rotation), then PPE as the last line of defence. A question offering "wear a respirator" as the best control for isocyanate exposure is usually a trap - engineering controls rank higher.

Elective units extend the core into specialised work: spray gun setup and maintenance, spray booth operation and bake cycles, advanced colour matching and blending, special-effect and multi-layer finishes, plastic and aluminium refinishing, paint defect diagnosis and correction, and small business or customer-service skills such as quoting and quality sign-off. Gun setup : fluid tip/needle/air cap combinations, fan pattern, atomising pressure, and the relationship between viscosity, temperature and flow. A wider fan with lower pressure gives better transfer efficiency but risks mottling. Booth operation : filter condition, airflow balance, booth cleanliness, flash-off between coats, and bake schedules per the product data sheet.
