Choosing the right paint is essential; look for products labeled as suitable for glass to ensure they will bond well and resist chipping or fading. These types of spray paints often contain special formulations that enhance durability and flexibility.

Applying thin coats rather than one thick layer can prevent drips and uneven application while promoting better adhesion. Allow each coat to dry before applying the next, as this helps build a solid, layered finish that adheres better to the glass.

Proper drying time between coats is important to ensure that the paint cures correctly and adheres to the glass surface. Following the manufacturer’s guidelines for drying times can help avoid issues with adhesion and ensure a smooth, professional-looking finish.
