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
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.

Note: Thick Paint Thickness will result in cracking.

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.

We have analyzed the film thickness data of over
11,000 vehicles and have found that the
measurements are below the automakers' specifications.

Low film thickness will cause paint failures.

Public Interest best served by a "Truth in Finish
Disclosure" with the purchase of any vehicle.

The automakers trust their suppliers.

Automakers, auto dealers and consumers should
receive a finish painted to their
