Understanding Panel Sections and Diagram

Back to Contents

Panel divisions in PDR

Just like in panel beating, there is an automotive industry standard whereby any vehicle is divided into specific sections in order to label similar parts into categories, left and right, front and rear to help assist in the quotation process and pricing structure.

L/C Left Cant Rail
R/C Right Cant Rail
R/F Right Front
R/R Right Rear
L/F Left Front
L/R Left Rear

The diagram of a typical vehicle has been colour coded to represent various panels. Each panel A to O have been labeled on the side matched to the colours – note the use of similar colours for specific pairs of parts such as the doors on the left and right side.

When we consider any vehicle, we look towards the front just like when we drive. Driver side is on the right R, front passenger is on the left L. And of course you have F designating the front, R representing Rear. U stands for Upper.


For example, panels N and O on the colour diagram below represent Left Front Door and Left Rear Door respectively.

Panel Sections

This diagram represents any possible vehicle. Obviously, not all vehicles are the same. You have 2 door vehicles, coupes, wagons, vans and so forth. The table below lists all vehicle styles.

Vehicle Style Features and distinguishing parts
4 door sedan 4 doors
2 door coupe sedan 2 doors
3 door hatchbacks 2 doors and rear hatch; upper tailgate
5 door hatchbacks 4 doors and rear hatch; upper tailgate
3 door wagon (incl 4WD) 2 doors and rear door; upper tailgate
5 door wagon (incl 4WD) 4 doors and rear door; upper tailgate
2 door single cab ute ute with panels; LH RH Pillar
4 door dual cab ute ute with panels; LH RH Pillar
2 door single cab ute with tray tray rather than panels; LH RH Pillar
4 door single cab ute with tray tray rather than panels LH RH Pillar

Some style of vehicles require elimination of some components. For instance, a 2 door sedan has only 2 front doors. On a quote sheet for a 2 door sedan, the diagram will have both rear doors crossed out as they don’t exist, namely parts K and O on the coloured sheet above. Note also, part E the upper tailgate only exists on wagons, hatchbacks and 4 WD vehicles. Utes have left and right hand pillars which would be noted as left and right quarter panels on the sheet L and P respectively.

A knowledge of the styles are important to note in relation to the panel diagram above, counting dents and quotation. It is very important that a system is used to quote in a specific order you find comfortable because of the various styles of vehicles, you may write down the incorrect number of dents in the wrong section on the diagram. This will alter the overall quotation based on the matrix.
