10 Easy Steps on How to Fix Spider Cracks in Headlights

Step 1. Clean the Lens:

Begin by cleaning the lens with a headlight cleaner or polish. This will help remove any dirt, grease, and grime that may have built up on the lens. If the lens is severely cracked, you may want to use fine sandpaper to help smooth out any sharp edges.

Step 2. Cover the Cracked Areas:

Once the lens is clean, cover the cracked areas with particulate masking tape to prevent any further damage. You can use a template to help you apply the tape in even strips. This will also help you ensure the tape is applied correctly and evenly.

Lightly Sand the Area of the Lens

Step 3. Sand the Area:

Using sandpaper, lightly sand the area of the lens that was covered with tape. This will help smooth out any uneven surfaces and make applying the protection film easier. Try to sand in one direction only to avoid damaging the lens.

Step 4. Clean Again:

Once you have finished sanding, use a damp cloth or sponge to remove any dust particles from the surface of your headlight lens. Make sure that all dirt and debris are removed before continuing with your repair work. Additionally, you may want to use a cleaner or polish again if necessary.

Step 5. Apply Protection Film:

Carefully apply the clear headlight protection film to the cracked areas. Use a razor blade or sharp knife to trim away any excess film if necessary. Repeat steps two through five on each cracked area of the headlights until all of them have been repaired. This will help ensure that they are fully protected from further damage and give them a new look.

Step 6. Wait for the Film to Set:

Allow the film to set for at least 24 hours so that it has time to properly adhere to the lens surface before you move on with your repairs. It is important to be patient and not rush through this step as it will ensure that your repair job is effective. As an additional precaution, you may want to place a soft cloth over the lens while it sets to prevent any dust from settling on it.

Step 7. Remove Tape & Film:

Once the protection film is dry, gently peel off both the tape and the film from the lens. Be careful not to scratch the lens surface when removing them. Otherwise, you may end up having to start all over again.

Step 8. Buff & Polish:

Using a clean cloth and headlight polish, gently buff and polish the surface of the lens to remove any residue left behind by the tape or film. You can use circular motions to help evenly distribute the polish and achieve the desired look. Always remember to be gentle and not press too hard when buffing or polishing the lens.

Using a Clean Cloth and Headlight Polish

Step 9. Reapply Film:

You can apply another layer of protection film for extra durability if desired. Allow this layer to dry for at least 24 hours before continuing with your repairs. Remember that the more layers of protection film you apply, the less visible your spider cracks will be.

Step 10. Clean Again:

Finish up your repair job by cleaning the lens one final time with a damp cloth or sponge. This will help remove any dirt or dust that may have been left behind during your repair work and give it an extra shine! Remember, it is always best to use a cleaner or polish if necessary.

And there you have it! With these ten easy steps on how to fix spider cracks in headlights, you can give your car a new look and protect it from further damage. Remember to be careful when handling sharp objects and always wear protective equipment such as gloves and safety glasses while working. If you have any questions or need help with your repair work, don’t hesitate to contact a professional for assistance.

5 Additional Tips and Tricks

1. Clean the headlight gently with soapy water and a microfiber cloth. Allow it to dry thoroughly before moving on.

2. Apply a thin layer of clear nail polish, super glue, or epoxy resin over the spider cracks. Let it dry for 15 minutes, and then lightly sand the area with medium-grit sandpaper to blend in the repair job.

3. Apply two layers of transparent tape (such as masking tape) on both sides of the headlight. This will ensure that the epoxy does not spread beyond where you intended it to go.

4. For larger cracks, apply a clear silicone sealant to help prevent water and dust from seeping in through the cracks and compromising your headlights’ performance.

5. For an even more effective fix, use a headlight restoration kit to restore your headlights’ clarity and reduce glare from oncoming traffic. Apply a coat of wax afterward for added protection from the elements.

5 Things You Should Avoid

1. Don’t use a power drill or any other metal tool for sanding the headlight afterward. This can cause further damage and weaken the plastic of your headlights.

2. Don’t apply too much epoxy, as it will not dry properly and may make the area look worse than before you started.

3. Avoid using clear nail polish for larger cracks, as it is not strong enough to repair them effectively.

4. Do not use duct tape, as it does not provide an airtight seal and can be difficult to remove without damaging your headlights further.

5. Don’t forget to read your product’s instructions carefully when using a headlight restoration kit! To ensure you get the best results, follow the manufacturer’s instructions and don’t skip any steps.

By carefully avoiding these mistakes and following the tips outlined above, you can easily fix spider cracks in your headlights.
