Reasons You Need Repair Kit for Your Windshield


The cost of a vehicle glass repair can vary between $20 and $200. Windshield replacement on the other hand can cost between $100 and $400. Although some damage to your glass will need to be checked by a professional, windshields do not need extensive repair. This is because windshields suffer minor damage.Since repairing your windshield does not warrant professional repair, you can buy a repair kit and fix the glass as soon as possible. You will find all you need for fixing the crack in the kit. The process is relatively simple; you just need to adhere to the instructions.

Things to Consider Before Buying a Repair Kit

You must consider some things before purchasing a repair kit. Knowing more about repair kits will definitely help you out to decide which repair windshield repair kit you need. Things you should consider include:

Assessment of the damage

Windshield Repair Kit

Assessing the extent of damage to your windshield is the first step to take. Check to see if it is cracked, chipped, or scratched. Also, assess how deep and extensive the damage is. This check is essential because it will help you know the exact type of kit that is needed for the repair. Most repair kits are limited and cannot handle extensive damage. Some kits can handle cracks better than chips. Only purchase the kit that matches the damage.

Assess the windshield to see the amount of pressure it can handle

In repairing a damaged windshield, you will need to insert the resin into the glass which will require that you put pressure. All kits require that you apply pressure. The design of the windshield makes it capable of handling much pressure. However, the glass can be weakened because of the cracks. It is therefore important that you assess how strong the windshield is before you go on to applying pressure.

Ensure that the kit has all components before buying it

You should make sure that the kit comes with some essential materials. Ensure that it contains a stabilizing device, resin, an instrument you can use to insert resin on the glass, and a cloth for cleaning. The time that it would take to cure the resin is another thing you should consider. It takes an average of 5 hours for the resin to cure.

Temperature sensitivity

A temperature range is needed to cure the resin patch. You will find the instructions on the best temperature range to repair the windshield repair kit. Some kits recommend that you cure the repair in direct sunlight and while others say otherwise. For the resin to properly cure, you must follow instructions.

Quality of resin

The windshield resin (learn more about this here) needs to be a high-quality substance for it to properly repair cracks and chips. A denser and thicker material that dries up easily should be what comes in the windshield repair kit. This property makes the resin blend into the windshield. Also, it will not leave any big blemish. A resin kit that is of low grade may dry in a pale yellow shade.

The size of the damage

To know the quantity of resin that will be needed to repair, you will first need to assess the volume of the cracks or chips. Normally, a small crack on a single windshield would only require that you use one repair kit for a one-time windshield repair. A kit that can be used more than one time will be needed if you are fixing multiple windshields.If you also need a car dent removal kit, check out our blog post here.
