Detailing is the process of thorough cleansing and decontamination of a vehicle followed by paint enhancement with machine polishing, making it ready to receive the wax and finishing dressings that will bring the vehicle to show quality. The focus is on quality of finish and attention to the tiny details, producing a better-than-showroom shine that other methods are unable to achieve.

The candidate will undergo a 3-day training process that covers every aspect of detailing, including (but not limited to): correct wash, clean and preparation technique, an understanding of paint, machine polishing, protection, interior detailing and finishing touches.

The candidate will carry out the detail work on the  vehicle with constant demonstration, supervision and appraisal from the trainer. Should the candidate be considering taking up detailing as a profession, discussion of the considerations needed for such a business with respect to costings, best practice and work flow will occur throughout each day of the training.

Although the training is laid out in three modules, the flow during each day will vary as the candidate learns, adapts and gains confidence.




This module covers all aspects of cleaning, decontaminating and preparing the vehicle for further work. It includes removal of tar, bird lime, brake dust, grease and other undesirable contaminants. it also includes discussion of product choices (such as the exclusive use of VOC compliant and biodegradable chemicals so as not to damage the vehicle or the environment) and efficiency/best cost practices vital to running a successful detailing business. The day concludes with interior detailing and the practices and products used.

To get that better-than-showroom shine any car on the road will benefit from paint correction, be it a light enhancement or full-on correction. This module covers the process from start to finish, from understanding how paints and lacquers are applied and assessing and recognising different paint types right through to machine polishing itself, and how it can remove light scratches, swirls, bird lime and tree sap marks amongst other imperfections to reveal the true lustre of the paint. Depending on the colour of the paint and density of clear coat the candidate will be shown the correct machine, pad and polish combination together with the correct techniques needed to enhance any car. The candidate will gain vital hands-on experience of both rotary and dual-action machines, and the benefits and limitations of both.

Paint Correction

The car is now clean and decontaminated, inspect the car for any re-spray work, accident damage, smart repairs, dents, major scratches, incorrect panel gaps or anything that would suggest that the car has had after market repair work to the exterior painted surfaces. Use of 3M automotive masking tape to cover all external exposed plastics and rubbers. Using a paint depth gauge take 2-4 readings per panel to help assess the paint depth and to confirm your visual inspection of any repair work. Use a torch to reveal the swirl marks on the paint work.

Using the a polisher with cutting pad & compound to correct the vehicle, panel by panel. Inspection of work to see correction results until desired level of paint enhancement is achieved.

Moving on to application of polish with polishing pad to vehicle, finishing with inspection of the paint work with a torch to confirm that the swirls are removed.
