Overspray: During the auto body work on the hood, paint or other materials used in the repair process may have accidentally oversprayed onto the windshield. These microscopic droplets can create the appearance of tiny pinpricks when the sunlight hits them at certain angles.
Sanding or polishing residue: If the auto body work involved sanding or polishing the hood, fine particles or residue from the process may have settled on the windshield. These particles can act as tiny lenses or prisms, causing the sunlight to scatter and create the pinprick effect.
Chemical residue: Chemicals used in the auto body repair process, such as cleaners, solvents, or degreasers, may have come into contact with the windshield and left behind a residue. This residue can alter the surface of the glass and cause it to diffract sunlight, resulting in the appearance of pinpricks.
Contaminants from the environment: After the auto body work, the vehicle might have been exposed to environmental contaminants such as dust, dirt, or pollen, which can accumulate on the windshield and cause the pinprick effect when backlit by the sun.
It's important to note that these tiny pinpricks may not necessarily indicate damage to the windshield's structural integrity. However, for clarity and safety, it is recommended to have the issue assessed by a professional auto glass technician. They can determine the exact cause of the pinpricks and recommend the appropriate solution, ensuring a clear and safe driving experience.
