How to Buy the Best Windshield Repair Kits
Before choosing a windshield repair kit, there are some important factors to take into account, which include the following.
1. Shape of damage
The shape of the damage will basically tell you if the windshield repair kit will be effective or not. Indeed, the windshield repair kit cannot repair any type of damage.
If your windshield crack is a star or flower shape, it can be easily repaired with almost any repair kit.
Basically, the star or flower shape will tell you that there is one main point of impact and the damage spreads outward from that central location.
Ensure that the central crack is no more than 1.5-in in diameter and the flower or star shape is less than 6-in in length for the repair kit to be effective.
Additionally, other types of windshield defects that the windshield repair kit can quickly and easily repair.
Luckily some kits like Gliston 13 are designed to repair almost any crack and chip shape.
2. Resin quality
Not all resin quality used in a windshield repair kit is the same. Some repair kits employ a higher grade resin that is thicker and denser and leaves a transparent finish that will blend perfectly with your windshield afterward.
On the other hand, a poor quality resin will cure in a yellowish color, which will make it apparent that you were trying to repair your windshield in the first place.
When purchasing a winter repair kit, look for terms like “Advanced Resin Formula” like what is included on the Rain-X 161890 to ensure that you are getting a high-grade and high-quality resin with your repair kit.
3. Sensitivity to temperature
Since your repaired windshield area will most likely stay in direct sunlight for an extended period of time sooner or later, it also needs to have a high sensitivity to temperature.
Check your instructions for any mention of temperature. Bear in mind that some resin formula may require an optimal temperature as well as exposure to direct sunlight for it to cure correctly.
The windshield repair kit volume is important for those who are planning to repair large or multiple windshields.
For the average person looking to repair only one windshield, the volume is irrelevant. Most of the time, a 1g resin tube is enough to completely repair a small windshield crack.
5. Easy to use
Not all windshield repair kits are the same. Some are easier than others. Ensure that your windshield repair kit comes with an instruction manual that will show you detailed steps on how to proceed like the Glass Polish GP21005.
Additionally, your windshield repair kit must also come with an applicator that will allow you to quickly and easily position your resin exactly over the cracked area on your windshield.
When it comes to the windshield repair kit, more accessories are always better than no accessories at all.
A good automotive glass repair kit will always come with accessories like cleaning cloth and an applicator that makes the whole process of repairing your windshield so much easier.
Hence, an all-inclusive one like the Tri Glass TRI 15 ,which comes with a wide variety of accessories, will always make an excellent buy.
How to Use Windshield Repair Kit
Step 1: Clean Your Windshield
Clean your windshield including the cracked area with a mild detergent and then wipe it clean.
Make sure that you remove all loose particles from the cracked zone before proceeding any further.
Additionally, inspect all areas that will require repair. Note that most windshield repair kits are most effective on windshield cracks that are around 1-in in diameter or less.
Step 2: Position your Applicator
Unpack the kit. Inside you will find a suction kit, called the applicator that positions itself directly over the cracked area of your windshield. Additionally, you will also find the resin tube which does the actual repair.
Once you have positioned the applicator directly over the cracked windshield, insert the extension base over the applicator so that it extends the applicator.
Step 3: Place Resin Tube inside Applicator
Place the resin tube over the applicator extension and tighten. You do not have to apply excessive force when tightening the syringe over the applicator extension, but it has to be fairly tight so that the resin replaces the air inside the applicator.
Finally, once the resin chamber is set, press the syringe so as to deliver around 6 to 10 drops of resin inside the applicator.
Step 4: Apply the Resin
Place the provided screw inside the resin chamber and screw it in a clockwise direction until it is tight. This will press the resin against your windshield very tightly.
Let it sit for around 5 to 10 minutes.
Step 5: Let it Cure in Direct Sunlight
After 5 to 10 minutes, unscrew and then remove the applicator kit entirely. You will find that the windshield has been repaired and that the resin has solidified.
Place the windshield in direct sunlight for a few hours. This will cure the resin. Once done, take a razor blade and scrape the excess resin off the windshield.
Finally, wipe the windshield clean with a clean cloth and you should have a repaired windshield that looks brand new.
Q: Does Windshield Repair Kit Really Work?
A: Yes, but it depends on the kind of damage or imperfections you are dealing with the size. Small dings, chips and cracks can be easily fixed with a windshield repair kit, but other things like shuttering and large cracks (more than 1.5-inch wide and 6 inches long) will be hard to fix.
Q: Is it Better to Repair or Replace a Damaged Windshield?
A: This will depend on the particular situation you are facing. If the glass is tempered, crack is longer than 6 inches and the chip or crack has penetrated deeper than halfway the thickness of the windshield, you are better off replacing it. Otherwise, if what you are dealing with is less intense than this, repair will be better.
Q: How do I Keep a Windshield Crack from Spreading?
A: The best way to stop a crack from spreading is to repair it immediately with the resin that comes with the repair kit. Also, avoiding sudden temperature changes for the windshield where possible can also prevent cracks from spreading.
As we have seen, the windshield repair kit is easy to use and will repair your windshield dames quite fast. But this is only so if you choose a good kit and our list above provides adequate recommendations.
And to help make a choice easier for you, the Rain-X 161890 is our best value product as it offers great service for its price.
However, the Rain-X 600001 takes our top overall recommendation spot thanks to the super fast curing and advanced resin formula.
