Best Windshield Repair Kit Buying Guide

What to Consider When Buying a Windshield Repair Kit

When looking at what window crack repair kit is best for you, it is good to bear a few things in mind before making your final purchase.

Firstly, assess the type of windshield damage that has occurred in the glass of your car. Different types of cracks and chips will need different types of repair, or sometimes even replacement. Plus, depending on the size of the crack will make a difference to the size of kit you need.

You will also need to ascertain how much pressure your windshield can take before it starts to crack even further – this is important as some pressure is required when repairing your windshield chip with a glass chip repair kit. If your windshield can only withstand a certain amount of pressure, then it will buckle whilst you are trying to fix it if you apply too much.

It is also good to inspect and double check what resin your chosen windshield chip repair kit has. For the best possible finish in terms of looks and how long it will last, the resin needs to be the correct type for the damage you have incurred. Lastly, always remember to smooth the resin on your window glass so that your wiper blades do not catch on any lumps or bumps that have been left behind. This can either undo all your good work or ruin your windscreen wipers.

Why You Should Purchase a Windshield Repair Kit

Cracks in windshields can be dangerous as if they get worse, the car becomes undrivable as visibility it so diminished – not to mention the risk of shards of glass flying in every direction.

Windshield Repair vs. Windshield Replacements: Which One is Better?

There is no question that a windshield repair is cheaper than a windshield replacement. Plus, not all cracks or chips require a replacement in the majority of instances. Whether they do or not is totally dependent on the following four factors. It is ultimately then up to the car owner to decide therefore whether to have the windshield replaced or repaired – but it is not a decision to take lightly as a windscreen cracking beyond any use whilst driving is incredibly dangerous for both the car driver and other cars on the ride.

  • The size of the crack – Any crack in your windshield that is longer than 18 inches or a foot and a half will result in the windshield having to be replaced. It is too prone to spreading otherwise and causing further damage as well as increased risk to the driver and passenger.
  • The depth of the crack – If a car windshield has been chipped deeper than 2 inches then the windshield will need a total replacement. The reason being is that repair anything that deep to a usable standard is incredibly difficult to night on impossible. Any repair that is made, simply won’t last and could cause greater costs in the future than having the windscreen replaced there and then.
  • The location of the crack – depending on where the crack is playing a huge part in whether the windscreen should be repaired or if it is better to replace it completely. Locations that call for a replacement are in the sight line of the driver – both at the front of the car and the back.
  • The type of damage incurred – this may sound odd but not all types of damage taken to a windshield can be repaired. Bullseyes or star breaks, as well as small chips, can all be repaired fairly easily. However, if you have been unfortunate enough to have acquired several types of cracks and chips, then there is a high chance that your windshield should be replaced. Speak to a professional in this instance.

If you do have to have your windshield totally replaced, there are more economical ways to do it than simply having it replaced with a new part from your car manufacturer at your local auto glass repair shop. Instead, try shopping around for a quote with local garages where you may be able to use an OEM part or an aftermarket part that has been refurbished. That being said, sometimes with a part as fundamental and important to the ability to drive a car, it is just easier and better, in the long run, to take the hit financially and have the windshield replaced as new. It’s expensive, but at least you can guarantee it will work and won’t cause your car any trouble in the future.

How to Use the Windshield Repair Kits

Windshield repair kits are easy to use, once you know how. Follow these steps to ensure you get the best possible finish when using one of the above from our windshield repair kit reviews.

  1. Pay attention to how big a crack or chip the repair kit tells you it can fix. Don’t try to force the issue as you could end up damaging your windshield more.
  2. Clean your windshield thoroughly and ensure that no debris is in or around the damaged area.
  3. Use your kit’s applicator and put over the chip or crack. There will be an extension base that needs to be inserted into the applicator.
  4. Put a syringe of resin over the applicator extension and secure it. This will remove all air from inside the applicator by creating a resin chamber.
  5. Start to syringe drops of resin into the applicator
  6. Put a screw from your kit into the chamber and tighten. This will spread and firmly press the resin into your windshield. Leave it there for up to 10 minutes.
  7. Unscrew the kit as the resin should have dried by now.
  8. The resin will need to be cured as per your kit’s instructions. This is often done through the use of direct sunlight.
  9. Remove any excess resin with a razor.

How to Keep a Windshield Crack from Spreading

There are a number of ways car owners can keep a windshield crack from spreading, other than buying the best windshield repair kit available on the market. However, the following ideas and tips are short-term solutions if you do not have a window crack repair kit to hand and can’t get to a technician’s quickly.

  • Use super glue. If the crack or chip is miniscule you can actually use superglue to stop the crack from spreading. It needs to contain cyanoacrylate and it needs to forced into the crack or chip in an even layer.
  • Use clear nail polish. This really is a very short-term solution, but it has been seen that nail varnish can actually stop a windshield crack from spreading. Apply it as you would to a nail, but make sure the surface is clean first and apply it generously. It needs to fill the crack as well as being spread around it so that the crack does not spread. This should buy a driver enough time to get a professional repair done.
  • Park in the shade. If you notice a chip in your car, but can’t get to an auto shop there and then, remember to park in the shade until it is fixed. The temperature of the sun can really affect the glass and therefore the crack within it. To protect against all weather, try to park inside whenever possible.

It is important to stress that these are only ever short-term solutions so that your car can be driven as quickly as possible either to a garage to have the chip repaired by a professional or to an auto shop where you can buy a glass chip repair kit so you can fix the chip yourself. Driving with a cracked windshield, whether you have protected it with super glue or not, can be dangerous both to you and others on the road around you.
