Considered a small damage containing scratched and scuffed panel areas without deforms of its original structure. Relatively easy and quick to repair through a sanding and optionally refilling missing, original panel material.
Medium to large type of damage caused usually by a stronger impact. Depending on the panel’s material type there are different rectification methodologies. Plastic panels are usually quite easy to be brought back into the shape using heat and light pulling techniques, while metal ones need usually get filled or get through a panel beating process before a respray.
In all of those cases panel needs to go through the resurfacing process with the use of fillers, sealers and primers before a respray in order to bring its surface to original smoothness and shape.
Medium to Large damage of the panel where the integrity of the panel surface is broken. The repair method is dependant on material type where welding may be required and in some cases refilling missing areas of the panel by integrating metal mesh into it which reinforces the panel itself.
It’s usually the most problematic issue and the biggest danger to the vehicle’s body. Once applied, rust will always expand, degrading the structure silently until it shows up on the surface as an ugly, red and bronze residue.
It appears in places where the bare metal material is exposed to moisture and water for a longer periods of time. Once applied it only can be removed by a complete extraction with a sanding or cutting methods.
Once rusted material is removed, the panel gets treated against it, resurfaced and resprayed. Bigger and deeper rust penetration is usually qualified only for costly body shop work.
Automotive paint spraying process involves multitudes of strong, chemical reactions wchich sometimes penetrates or separate from each other. Sometimes external factors or mistakes made in the preparation process result in disruption of those materials chemical properties.
That causes many types of issues like paint peeling off the surface, blisters, tarnishing, change of the colour properties etc.
Those issues can be thankfully resolved by removing all of the paint layers to the original panel surface and proper respray processes.
