Safety First!

Always select appropriate Personal Protective Equipment - Eyewear, gloves, hearing and respiratory protection for your job and workplace!

Step 1 - Clean the area

Apply 3M™ VHB™ Surface Cleaner or 3M™ General Purpose Adhesive Cleaner 08984 using 3M™ Professional Panel Wipe 34567 to clean the area. Allow to dry completely.

Step 3 - Increase the repair strength

Drill several holes of 3-6 mm in diameter in the remaining part of the tab to increase the strength of the repair.
Step 2 - Smooth rough edges

Use 3M Roloc™ Disc P80 to smooth rough edges of broken tab.

Step 4 - Apply Polyolefin Adhesion Promoter

Coat tab area in 3M™ Polyolefin Adhesion Promoter 05917 and leave to dry for 10 minutes.

Step 5 - Apply Superfast Adhesive

Cut a piece of 3M 4903 contour film about 2.5 times the size of the tab to be repaired.

Apply 3M™ Superfast Plastic Adhesive PN55045 transparent or PN04748 black using 3M™ Applicator 08190 and use the contour sheet as support.

Step 6 - Form the tab

Immediately fold the sheet and shape adhesive with fingers. Force adhesive into the drilled holes.Do not press too hard to keep a 3 to 5 mm layer of adhesive material on both side of the tab.

Caution: when starting to cure, adhesive becomes hot! The adhesive will set within 20-30 secs.

Let the adhesive cool down and peel off contour sheet.

Step 7 - Shape the tab

After 5 minutes shape tab using 3M™ Roloc™ Disc P80/P180 and create a new fixing point to restore original appearance.

Step 8 - Paint the tab if necessary

If necessary, 3M™ Superfast Plastic Adhesive 55045 / 04748 can be painted using the usual paint process for plastic parts or specific bumper paint in spray.
