Step 1: Remove the Part You Want to Repair
Start by removing the part you want to repair. Now take your repair kit and discard the plastic film.

Step 2: Prepare the Chemical Mixture
A tail light lens repair kit usually contains a material inside to repair the damage. To activate the chemical process, you need to mix the ingredients, like an epoxy. Once the mixture is complete, you must apply it as soon as possible to ensure its effectiveness hasn’t diminished. However, in all situations, you don’t need to panic, as you will have enough time to apply the mixture. Follow the instructions of the tail light lens repair kit.
