Review on 🚗 YOOHE Windshield Repair Kit - Auto Glass Chip Repair with Resin for Fixing Windshield Crack, Chip, and Scratch by Brian Rivera

I got a crack in my windshield while driving on the Autobahn the other day. I bought this kit and followed the instructions as best I could as they are written in very poor English. First I cleaned the surface of the crack with alcohol and let it evaporate before beginning the procedure. I then placed the base with the suction cups in the center of the crack. The next step is to screw in the hose to allow the resin to flow until the plastic lip is pressed firmly against the windshield to avoid resin spillage. I put 5 drops of resin in the chamber and then use the included screw to push the resin into the crack. I noticed a large air bubble over the crack so I took out the screw and reinserted it several times hoping to get rid of the air bubble but it didn't (see attached pictures). I couldn't get the resin to flow fully into the crack either - using a heat gun definitely helped (higher temperatures seem to lower the resin's viscosity, making it flow more easily at the same pressure). I was doing repairs in my garage on a cloudy/snowy day in 40 degree weather. I used UV light to speed up the curing process and then scraped off the excess resin with the included razor blade. The repair looks decent but I was not able to drain the resin completely through the crack hence the 3 star rating.
