For Best Results

First, read the instructions twice and watch the 5-minute video of the company on You Tube (search for “Blue Star Windshield Repair”). The video makes clear certain things: “tabs aligned” means aligned rotationally, not vertically.

In addition, there should be some adhesive pad tab sticking up above the pedestal tab when the latter is perfectly centered on the adhesive pad.

For best results, you should take a very methodical approach and make sure the pedestal is FIRMLY attached to the adhesive pad, and that the pin valve is REALLY sealed well.

Next, you should let the resin set under pressure in the pedestal for two full hours, not 20 minutes as recommended.

Finally, let the resin cure under the curing film for two hours on a day with passing clouds, not the 15 – 60 minutes recommended in the instructions leaflet.

Factors To Consider When Buying A Windshield Repair Kit

If you plan to go shopping for a windshield repair kit any sooner, you should consider the following key factors:

1. Shape Of Damage

Which windshield repair system will work best for you depends on the specific shape of the damage you want to treat. However versatile the solutions reviewed above may be, no system works equally well on just any sort of crack.

2. Resin Quality

Not all resin types used in windshield repair kits are of the same quality. Some repair kits boast a higher-grade resin that is a bit denser, and it also leaves a transparent finish which blends perfectly with your windshield after the repair.

Watch out, because a poor-quality resin will cure in a yellowish color which will make it apparent that you have been trying to repair your windshield on your own.

3. Temperature Sensitivity

Since the repaired windshield area will most likely stay in direct sunlight for an extended period of time, it also needs to have a reasonable sensitivity to temperature. Check your instructions for any mention of temperature.

Bear in mind that some resin formulate may require a specific temperature, as well as exposure to direct sunlight, so as to cure properly.

4. Quantity

The quantity of the active substance in your windshield repair kit is important, especially if you are planning to repair larger or multiple windshields.

On the other hand, if you need the kit for one-time repair, the quantity of the resin is irrelevant. In most cases, a 1g resin tube is enough to completely repair a small windshield crack.

5. User Friendliness

Some windshield repair kits are easier to use than others. Ensure that your windshield repair kit comes with an instruction manual that will show you how to proceed.

Your windshield repair kit must also come with an applicator that will allow you to quickly and easily position the resin exactly over the cracked area of your windshield.
