Bright Work Polish vs. Nuvite

Bright work polish

nuvite polish
Purpose
Which product shines brighter?
Scope
tools
The goal for this comparison
is to determine which product
polishes aluminum and leaves a
more reflective shine. By using a
scientific tool, called a gloss meter,
we can test the reflective index of
the aluminum surface before and
after polishing to determine the
level of light being reflected. The
higher the level of reflectivity, as
measured by the gloss meter, the
better quality of the shine.
Standard tools are used during
this test, which include a Dewalt
DWP 849X high speed buffer, a
Porter Cable 742XP orbital buffer,
SM Arnold wool pads and cotton
felt for final polishing.
Test equipment
A three angle gloss meter was
purchased from FRU, model
number WG68. This instrument
can measure up to 2000Gu at
20 degrees, which is required to
test a metallic surface (such as a
mirror). Read more about it at

gloss meter to see how one works.

Test equipment
We first located a test piece of aircraft skin, which happens to be a removed
wing leading edge skin from a Challenger 604. We designated two different
polishing areas on the skin, one for Bright Work Polish and the other for
Nuvite. During each phase of our test a reading was taking with the WG68
to measure the Gu or reflective value. The higher the number the more
reflective the surface. The first image is the skin prior to polishing.

As you can see this aluminum skin is
very oxidized and is an excellent test
material for both products.

This is the first reading with the
FRU gloss meter on the oxidized
aluminum skin which resulted in a
reading of 617.5 GU at 20 degrees of
angle. This is our starting number,
as the test number increases the
surface reflectivity increase also.

This is a reading with the FRU gloss
meter on the aluminum skin after it
was polished with Bright Work Polish
Red Step 1. The result was a reading
of 823.7 GU at 20 degrees of angle.
Red Step 1 cut through the oxidation
very quickly when used with a high
speed buffer and a wool pad. The
goal was to remove all the oxidation.
The result show a better shine from
Bright Work Polish as tested with the
gloss meter.

This is a reading with the FRU gloss
meter on the aluminum skin after
it was polished with Nuvite F7. The
result was a reading of 794.0 GU at
20 degrees of angle. Nuvite also cut
through the oxidation quickly, but
the gloss meter test resulted in a
lower number with F7, meaning the
shine was not as good as the Bright
Work Polish.

The next polish step in the Bright
Work Polish line is the Bright Work
Polish White Step 2. This is a reading
with the FRU gloss meter on the
aluminum skin after it was polished
with Bright Work Polish White Step
2. The result was a reading of 1372.5
GU at 20 degrees of angle. A high
speed buffer and a new wool pad
was used which resulted in a higher
GU number when tested against the
Nuvite C. Step 2 provided a dramatic
increase in shine in both product
tests with the gloss meter.

The next polish step we tested in the
Nuvite is the C. This is a reading with
the FRU gloss meter on the aluminum
skin after it was polished with Nuvite
C. The result was a reading of 1193.6
GU at 20 degrees of angle. Nuvite
C provided a dramatic increase in
shine in both the test with the gloss
meter and visually. A high speed
buffer and a new wool pad was used
which resulted in a lower GU number
when tested against the Bright Work
Step 2.

The next polish step in the Bright
Work Polish line is the Bright Work
Polish Blue Step 3. This is a reading
with the FRU gloss meter on the
aluminum skin after it was polished
with Bright Work Polish Blue Step 3.
The result was a reading of 1565.9
GU at 20 degrees of angle. At this
point an orbital polisher and a cotton
felt pad was used. This combination
removed all the fine scratches and
left a mirror finish. The test results
prove that Bright Work Polish Step
3 has a higher reflective value over
Nuvite S.

The next polish step tested in the
Nuvite line is the S. This is a reading
with the FRU gloss meter on the
aluminum skin after it was polished
with Nuvite S. The result was a
reading of 1442.6 GU at 20 degrees
of angle. At this point an orbital
polisher and a cotton felt pad was
used. This combination removed the
fine scratches and left a great finish.
But, the test results prove that Bright
Work Polish Step 3 has a higher
reflective value over Nuvite S.

in Conclusion
The FRU Gloss Meter scientifically proved that the Bright Work Polish
produced a more reflective surface during each 3 steps of the polishing
process. Visually the Bright Work Polish provided a deeper shine during
each step and cleanup was much easier. Both product do produce a
brilliant shine on the aluminum skin but in all tests the Bright Work Polish
resulted in a better finish.
bright work polish wins!
