How To Fix Broken Side Mirror Plastic

How to Fix Broken Side Mirror Plastic

A broken side mirror plastic is a common automotive problem that can be frustrating and potentially dangerous. While a cracked or shattered mirror can obstruct your view, a completely broken plastic housing can render the mirror unusable. This article provides a comprehensive guide on how to fix broken side mirror plastic, offering practical solutions for various types of damage.

Assess the Damage

The first step in fixing a broken side mirror plastic is to assess the extent of the damage. This will help you determine the most appropriate repair method.

Cracks and Scratches: Minor cracks and scratches can often be repaired using epoxy resin or a clear coat sealant. This method is effective for surface-level damage that doesn't compromise the structural integrity of the plastic. However, deep cracks may require more extensive repairs.

Shattered Pieces: If the mirror plastic is shattered into multiple pieces, it's advisable to replace the entire housing. While adhesive bonding may seem possible, it's often not a practical or durable solution for extensive damage.

Missing Pieces: Missing plastic pieces can be tricky to repair, depending on the size and shape. Small gaps may be filled with epoxy resin or a plastic repair kit. However, for larger missing sections, a replacement part may be necessary.

Repair Methods

Once you have assessed the damage, you can choose the appropriate repair method. Here are some common approaches for fixing broken side mirror plastic:

Epoxy Resin

Epoxy resin is an effective adhesive for repairing cracks and small gaps in plastic. This two-part compound hardens into a strong, durable bond. To use epoxy resin:

Clean the affected area thoroughly with rubbing alcohol or a cleaning solution.
Mix the epoxy resin according to the manufacturer's instructions.
Apply the resin to the crack or gap, ensuring it fills the void completely.
Clamp or secure the parts together for a few hours to allow the resin to harden.
Once the resin is fully cured, sand and smooth the repaired area for a seamless finish.

Plastic Repair Kit

A plastic repair kit typically includes a two-part plastic welding compound, a mixing tip, and a scraper. This method is ideal for joining broken plastic pieces or filling larger gaps.

Clean the broken edges of the plastic with rubbing alcohol or a cleaning solution.
Mix the plastic welding compound according to the manufacturer's instructions.
Apply the compound to the broken edges, ensuring a strong bond.
Use the scraper to smooth out the compound and create a seamless transition between the broken pieces.
Allow the compound to harden before sanding and finishing the repaired area.

Replacement Housing

If the damage is too extensive or the plastic is beyond repair, replacing the entire side mirror housing is the most practical solution. This involves purchasing a new housing that matches your vehicle's model and specifications.

Installation: The process of installing a new side mirror housing varies depending on the vehicle. However, the general steps involve:

Remove the old side mirror housing from the vehicle using a screwdriver, socket wrench, or other appropriate tools.
Align and install the new housing, ensuring proper fit and functionality.
Tighten the mounting bolts or screws securely.
Adjust the mirror angle to ensure optimal visibility.

Tips for Maintaining Side Mirror Plastic

Preventative measures can help minimize the risk of side mirror plastic damage. Here are some tips:

Park Safely: Avoid parking in tight spaces or areas where your vehicle could be bumped by other cars.
Use a Car Cover: A car cover can protect your vehicle from dust, debris, and potential damage from the elements.

>Clean Regularly: Wash your vehicle regularly and use a gentle cleaning solution to avoid damaging the plastic.

Avoid Harsh Chemicals: Avoid using harsh chemicals or abrasive cleaners on your side mirrors, as they can weaken the plastic.

Be Mindful of Sharp Objects: Avoid using sharp objects or tools near your side mirrors, as they can easily scratch or damage the plastic.
