Will a small windscreen chip spread if I leave it?

A dangerous delay in maintenance occurs because drivers trust the idea that **if a stone chip does not crack immediately it will remain stable**. This misunderstanding results in many preventable full-windscreen replacements. Glass is a brittle material, and a chip represents a breach in its surface tension—a "ticking time bomb" waiting for a trigger. Vibration from driving, chassis flex when cornering, or a simple door slam can introduce enough energy to turn that stable-looking chip into a catastrophic crack instantly. There is no such thing as a "safe" chip, only one that hasn't spread yet. MOD5 TopShield windscreen protection film serves to reduce the likelihood of these deep chips occurring. For owners, the takeaway is that visibility does not equal stability; any surface compromise is a structural risk. Knowing this, TopShield users rely on the film to prevent the initial penetration that leads to this instability.
