How to repair a car wing mirror

This guide will show you how to fix a broken car wing mirror. Sugru Mouldable Glue creates a strong bond between broken surfaces and can cover cracks and fill gaps, saving you an expensive trip to the mechanics!


  • A cracked wing mirror
  • A single-use pack of Sugru
  • Soapy water
  • Toilet/tissue paper

Step 1

sugru used to cover crack in mirror casing

Ensure the broken surface area is clean and that the crack is pushed closely together. Roll your Sugru into a sausage and place it over the length of the crack. If you find that the Sugru sticks to your fingers, use some tissue paper to rub it off.

Step 2

sugru edges smoothed over with finger

After placing the Sugru over the crack, smooth out the edges with your finger. Sugru bonds most securely when you are unable to see a shadow or gap where the Sugru and the plastic meet.

Step 3
