The most common minor car accident is when you (or another driver) clips your wing mirror and shatters your wing mirror glass. But fear not, if it's just the glass that is cracked, then you can replace it at very little cost or effort. Replacement mirror glass is different for most car makes / models as it designed to an exact shape, but it is available for most cars and vans, without having to replace the full wing mirror.
Your wing mirror glass is stuck onto a backing plate which in turn is attached onto the wing mirror body. The mirror glass can be purchased on its own or with the backing plate. If you find that your wing mirror glass is cracked you have two options:
1: if the glass is cracked but is securely attached onto the backing plate you can simply stick new mirror glass onto the old glass. The adhesive on the back of the mirror glass is extremely strong and the replacement glass will stick on securely.
2: if your existing glass is badly cracked / damaged, you can scrap it off the backing plate and then stick your new replacement mirror glass directly onto the backing plate, again using the adhesive on the back of the mirror.
