repair process, personal protection is a must. Remember to wear protective eye wear, gloves,
hearing protection, respirators, and protective clothing based off your exposure assessment.
For paint finishes that contain minimal dirt defects and a texture that matches adjacent
panels, the best way to remove defects is to sand the surface with a dual action sander
Equipped with the proper abrasive, a 3 inch dual action sander is recommended with paint
jobs for just a few small dirt defects that need to be removed. This keeps the repair
as small as possible. First, locate the paint defect that needs to be removed. Attach a
3 inch 3M brand Purple Finishing Film Hookit Brand P1500 or P2000 grade disc to the 3 inch
DA sander. A soft interface pad is recommended, but not required. Sand the defect until it
is removed. When all the defects have been removed, wipe the sanding dust off the paint
before moving to the next step. In this step, you're refining the sand scratches created
by the P1500 or P2000 grade finishing film abrasives in the denibbing and texture-matching
step. For spot repairs, a 3 inch dual action sander is recommended to keep the repair area
as small as possible. Using a 3M Trizact brand 3000 disc on a dual action sander with an
interface pad, spray the disc and the surface to be sanded with water using a spray bottle.
Using Trizact 3000, it is recommended to be used damp, not wet. Sand with medium pressure
using 5 to 6 overlapping passes until a light slurry covers the repair area. Cross-sanding
with the dual action sander creates a uniform finish. Clean the surface with a microfiber
towel and inspect the surface to insure scratch refinement is complete. Once this initial
scratch refinement step with Trizact 3000 is complete, you're now ready to move on to
further refining the sand scratches in the next step. To obtain the ultimate finish and
eliminate the compounding step, scratch refinement with Trizact 8000 is required. With this step,
you're refining the sand scratches to the point where you actually get to polish the
paint, eliminating the need for compounding, which means no more swirl marks. For spot repairs
using a 3 inch dual action sander is recommended to keep the repair area as small as possible.
Using Trizact 8000 on the dual action sander with an interface pad, spray the disc and
the surface to be sanded with water using a spray bottle. When using Trizact 8000, it
is recommended to be used damp, not wet. Sand with medium pressure using 5 to 6 overlapping
passes until a light slurry covers the repair area. Cross sanding with the dual action sander
creates a uniform finish. Clean the surface with a microfiber towel and inspect the surface
to ensure the scratch refinement is complete. Once the scratch refinement is complete, you're
now ready to move on to further eliminating the sand scratches in the next step. The most
unique aspect of the 3M Trizact 8000 disc is that it eliminates the need to use compound.
Your only polishing step is with 3M Perfect-it brand 1-Step Finishing Material and with 3M
Perfect-It 1-Step Foam Polishing pad. Attach a purple, 4-inch, 3M Perfect-It 1-Step Foam
Finishing Pad to a 3 inch polisher. Apply polish to the repair area and polish with medium pressure.
Reapply polish and repeat if sand scratches still remain.
