Instructions

Step-by-step for headlight repairs

Step 1: Prepare the surface

Before you can fix your car headlight, you must clean the area to ensure it is free from dirt, dust or debris.

Step 2: Cut a piece of tape

Measure a piece of tape about 1 or 2 inches longer than the cracked section. Use a pair of scissors to cut the tape, trying not to touch too much of the exposed adhesive side. 
Good to know: Before cutting the tape, place a toothpick or paper clip on the sticky side. This will make it easier to find the end next time - saving you time and frustration!

Step 3: Press the tape over the crack

Press one end of the tape on the surface of the headlight just beyond the start of the crack. Keep pressing down firmly as you lay the rest of the tape over the crack and make sure there are no air bubbles.

Good to know

We recommend pressing the tape into place for approximately 30 seconds to activate the adhesive. It is ready for use immediately, but the adhesive will attain its full strength after 24 hours of curing. 

Step 4: Ta-da!

You've now repaired a cracked headlight using Bostik's high performance, clear duct tape, Max Repair Tape. The tape is now securely in place, forming a strong, clear seal over the damaged area.
