Automotive painting is a science.
A typical finish consists of four layers:
1) electrocoat - provides corrosion protection
2) primer - protects electrocoat, stone chip resistance, adhesion
between basecoat and elctrocoat
3) basecoat - provides color to the vehicle
4) clearcoat - sunlight protection, scratch resistance, gloss
and appearance properties
Film thickness is a criteria used by the auto industry to ensure durability.
Each of the 4 layers must be at the proper film thickness specification.
If any of the individual layers is below specification. The vehicle would
be considered a factory paint defect.
A visible manifestation of low film thickness is paint peeling, body rusting and stone chipping.
Since the mid 1990s the auto industry while retaining ownership of the paint facilities have outsourced
the process and quality responsibilities to multiple paint suppliers.
Outsourcing in this application is defined as a process in which a company
assigns its in-house operations to a third party.
Specifics on automotive paint suppliers roles within the facilities may be found in textbooks published
both in Europe and America. The most recent textbook being released in 2008.
The paint suppliers actively market and advertise their outsourcing expertise with terms such as
"Cost Per Unit" or "Pay As Painted" supplier programs. Outsourcing [Cost Per Unit] programs are
common throughout Europe and America within the auto industry.
Not all vehicle flaws are associated with the paint itself, vehicle design and weathering will
impact the vehicle's finish.
It is our opinion that the automaker, auto dealer and consumer should not receive a vehicle painted
below the automaker's film thickness specifications of any of the four layers that comprise a vehicle's finish.
Low film thickness will cause paint failures.
