Most of the parts we receive for restoration
show the wear of over 40 years of use. Dented,
dull and scratched parts are the norm.
Each part is engraved with a job number on
the back to ensure the part sent in is the
same part that is returned to the customer.

We are now ready
to begin working on the old bezel. The first
step is removal of the original paint with
a chemical stripper that is speciallly formulated
to effectively remove the paint without harming
the underlying metal.
|
| |
|
|
The next step in the process
is the removal of the old anodized finish
buy soaking it in a chemical bath.
This critical process requires a special
chemical composition that will remove the
anodizing without harming the underlying metal.
WARNING: NEVER USE A COMMON
ANODIZING REMOVAL CHEMICAL, YOU MAY HARM THE
METAL
The cleaned part is shown, ready for the
next step in the process. |

Now we are ready
for the critical dent removal process and overall
cosmetic restoration. Over the years we have
accumulated an inventory of special checking
fixtures that allow us to accurately measure
the dimensions and be sure your piece is not
out of shape as we remove dents and straighten
it.
The dent removal process requires a skilled
experienced hand. From the back side we will
push the metal proud of the original surface.
This raised area is then sanded and polished
back to it's original position. This is a
metal removal process, and too much sanding
can result in a metal burn through hole. A
hole in the trim can only be repaired by welding.
This is a problem since an anodized weld will
have a different color than the rest of the
piece. |
| |
|
|
Once the dents
are removed, the sanding and polishing begins.
We sand the piece on a belt sander progressively
using finer and finer grits with grease to
acheive the correct surface finish.
Polishing
Now it's time to polish the piece. Different
trim components can have different polishing
requirements. The first step is the "Cutting
Process" which requires a wheel
/ rouge combination that will remove aluminum.
The cutting process is followed by the "Coloring
Process". This requires a different
wheel / rouge combination that will bring
the correct color back to the piece. |
| |
|
|
Now the piece is sent out
for anodization, an electrochemical
process that converts the surface to a structured
form of aluminum oxide that gives it a stable
protective coating with a high sheen.
Finally the part is painted if required by
the piece application. The anodized surface
is perfect for paint adhesion, so no priming
is needed. |
