3M trizact finesse-it paint defect repair system brochure Manual De Usuario

• Start the tool on the work surface. Do not

“free spin” the tool. The Dynabuffer air line
pressure needs to be set at 80 to 85 psi
while the tool is running.

• Polish with a downward force not to 

exceed 5 lbs (the tool weighs 3 lbs).
This is enough force to compress the 
peaks of the foam pad.

• Keep the buffing pad flat. Do not tip it 

on edge.

• If polish is being slung outside of the repair

area, either too much polish is being used 
or not enough downward force is being
applied. Reduce the amount of polish being
applied or slightly increase the downward
force being applied.

• Stop the tool before removing it from the

work surface. Do not “free spin” the pad.

Sanding

• Use water as a lubricant during

sanding. Spray the abrasive disc with
water before and after sanding each
spot to keep the disc clean and extend
its life. Make sure the backup pad is dry
when replacing the disc.

• Sand in a small circular motion with the

pad flat against the surface.

• Avoid over-sanding. Use a light

feathering technique. Keep the sanded
area as small as possible.

• Use extra caution to prevent over

sanding when machine sanding near
the edges of panels, which are less
flexible and typically have thinner
coatings. If preferred, these areas can
be hand-sanded.

The 3M

™

Trizact

™

Finesse-it

™

Paint Defect Repair System gives you a

faster, easier way to make high-quality repairs of minor clearcoat defects,
such as dust and minor scratches.

The Finesse-it system uses advanced 3M abrasive technology to quickly
remove imperfections, then polish out fine sanding scratches in just two
simple steps – making conventional 3 and 4-step repair methods obsolete.

The secret of the fast, fine and predictable finish of the Finesse-it 
system lies in the unique construction of the 3M

™

Trizact

™

Finesse-it

™

Film Disc 466LA. 

Using patented 3M microreplication technology, micron-graded silicon
carbide particles are formed into tiny pyramids of abrasive mineral, then
coated on a non-compressible polyester backing. As these pyramids wear,
fresh, sharp mineral is continually exposed to give you a consistent cut and
a predictable, fine finish.

In addition to high-performance abrasives, 3M microreplication technology
is also used in the manufacture of a variety of 3M products such as
overhead projector lenses, reflective traffic signs and solar optical films.

Paint Repair System is not appropriate for all

paint defect repair applications. For recommendations on how to repair
larger areas, contact the 3M Customer Response Center at 866-279-1235.

For successful results, make sure:

• The defect is minor – such as dirt, lint or small craters
• The area needing repair is small
• The paint surface has little or no orange peel

The buff pad only needs to be conditioned when it is new. 
To condition the buff pad, apply “chocolate chip”-sized
drops of the appropriate polish to the valleys on the buff
pad. After the polish has been applied to the buff pad,
fold the pad in half and apply pressure. Open the pad
and rotate 90°, then fold buff pad in half again and 
apply pressure.
