The 3M™ Automix™ EZ Fix Flexible Patch is used in conjunction with 06396 adhesion promoter to reinforce the inside of a "two sided" plastic repair: (damage that penetrates through the plastic material)
The outside of the repair is performed using traditional cosmetic flexible plastic repair procedures. 05888 will exhibit similar characteristics to TPO type bumper plastics; it is flexible yet strong, and uses acrylic foam tape technology (06396 foam tape adhesion promoter must be used) to adhere to the plastic and reinforce plastic that has been cracked, torn, or perforated during a collision.
Directions for Use
1. This procedure is for tears, punctures, holes and other damage that require front and backside reinforced repairs. The repair procedure uses the new, patent-pending 3M bumper patch.
2. Clean the panel thoroughly on both sides with soap and water first, then followed by 3M General Purpose Adhesive Cleaner (PN 08984, 08986 or 08987)*.
On the back side of the bumper, it is critical that all paint overspray be removed in the area where the patch will be placed. This paint overspray has a weak bond to the bumper plastic and can lift off easily if not removed.
3. This step is only if you are repairing a crack that has reached to the edge of the bumper plastic:
Before proceeding with the repair, grind a v-notch at the edge of the crack. This will keep the crack from propagating later in the procedure.
4. Wipe the back side of the bumper where the patch will be placed with 3M Automotive Adhesion Promoter (06396). Allow this to dry for 5 minutes.
5. Cut to size, remove the release liner, and apply the new 3M bumper patch to the backside of the bumper. Press in place firmly, as pressure will increase the bond strength. If the full-size patch is too small for the damage you are repairing, this is not an appropriate repair to make with the patch.
6. On the front side, use a grade 50 Roloc disc to dish out the crack or bevel the sides of the hole.
It is okay to dish into the bumper patch tape, but take care not to grind all the way through the patch itself. Also take care not to abrade areas on the front side of the bumper that will not be covered by repair adhesive in a later step.
7. Switch to a grade 80 DA disc and continue to dish out the repair on the front side, insuring that there are no sharp edges that will cause the repair to be visible once completed. Finish the dishing out and blending into the undamaged area with grade 180 DA paper.
8. Blow off the repair piece using clean, un-oiled compressed air.
9. Spray the front side repair area with 3M Automix Polyolefin Adhesion Promoter (05907) and allow to dry for 5 minutes.
10. Apply 3M EZ Sand Flexible Parts Repair (PN 05887) in thin layers to the front side of the repair piece, building it up until it is slightly higher than the surrounding area. Allow 15 minutes to continue.
11. Check to be sure the material is ready for sanding, and use a grade 80 DA disc to bring the repair material almost level with the surrounding area. Switch to grade 180 to blend the repair material flush with the panel, and finish with grade 320.
12. Reapply 3M Automix Polyolefin Adhesion Promoter (05907). Prime and paint per paint manufacturer recommendations.
