Car mirror glue:  The DIYer’s guide to fixing broken side mirrors

Busted side mirror? A visit to the mechanic will cost you big bucks – so repair or replace it yourself using car mirror glue. Read our guide to find out how to use automotive silicone mirror adhesive and epoxy glues for car side mirror repairs.

How to choose a car mirror glue

So you’ve decided to repair a broken side mirror yourself. But how do you choose the right car mirror glue? Well, it depends on the materials you’re working with. Luckily, that’s easy to find out – simply check the back of the mirror and/or the mirror housing where you’ll reinstall the mirror.

Some repairs might require an epoxy glue for car side mirrors, which are suitable for many materials you find on vehicles, like metal, glass and plastics. Loctite Epoxy Gel is a great choice - the non-drip gel formula creates tough, rigid bonds in just six minutes, making it perfect for use on vertical and outdoor surfaces like your car side mirror. Epoxies are great for repairing mirror housings, too.

When it comes to repairing cracks or breaks in the mirror itself, we recommend using automotive silicone mirror adhesive, which remains elastic and is resistant to moisture and weathering, making it a great choice for repairing car side mirrors that are exposed to the elements. Just make sure that the automotive silicone mirror adhesive you choose to work with is formulated for outdoor purposes.
