Paint Finishing Without Rubbing Compound – How to Use 3M™ Perfect-It™ 1-Step Paint Finishing System


3M is excited to introduce our latest generation
of premium paint finishing products, providing you with an easy-to-follow process to achieve
a defect-free finish. For those desiring more technical details
about each process step, please visit our website. As in any auto body repair process, personal
protection is a must. Remember to wear protective eye wear, gloves,
hearing protection, respirator, and protective clothing based on your exposure assessment. When sanding is required to remove texture
and paint defects throughout an entire panel, using a 6 inch dual action sander is the most
productive method. Attach a 3M brand Purple Finishing Film grade
P1500 or P2000 grade disc to the sander. A soft interface pad is recommended, but not
required. Sand the panel until the defects are removed
and the texture is level to match adjacent panels. When the desired results are achieved, clean
the sanding dust off the panel before moving to the next step. In this step, you’re refining the sand scratches
created by the P1500 or P2000 abrasives in the denibbing and texture-matching step. 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. When 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 ensure the scratch refinement is complete. Once this initial scratch refinement 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 a 3M Trizact 8000 disc is required. With this step, you’re refining the sand scratches
to the point where you actually begin to polish the paint, eliminating the need for compounding,
which means no more swirl marks. Using a Trizact 8000 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. 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
are 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
1-Step Finishing Material and the 3M Perfect-It 1-Step Foam Polishing Pad. Attach a purple 3M Perfect-It brand 1-Step
Foam Polishing Pad to the buffer and set the polisher between 1200 and 2000 rpm. Apply polish to the repair area and polish
with medium pressure. Remove any residual polish off the panel using
a different microfiber cloth and inspect to ensure the finish is perfect. Reapply polish and continue buffing as needed. For more information, visit our website at
