After repairing a windscreen chip or crack with epoxy resin, many wonder if further work is needed to restore clarity or smoothness. Here’s how to achieve the best finish on glass without causing damage.
Assessing the Repair Area
Once the epoxy has fully cured, carefully inspect the repaired section. Ideally, a successful repair will leave a nearly flush surface, but sometimes a little excess resin remains above the glass. At this stage, try gently scraping any raised spots with a plastic blade. Avoid metal tools, as these can scratch the glass.
Should You Sand or Polish?
In most cases, aggressive sanding is not recommended. Glass is easily scratched, and sanding may dull the surrounding area, making the repair more noticeable. If a slight haze appears after scraping, consider using a mild glass polish and a soft cloth to restore clarity. Work gently and test a small spot first to prevent further damage.
Practical Tips for a Discreet Finish
- Work slowly and use only gentle, non-abrasive methods.
- Plastic blades or cards are optimal for excess epoxy removal.
- Choose a glass-specific polish for minor hazing, following the manufacturer’s directions.
- If you’re unsure, consult a repair specialist for advice.
When This Matters
Perfecting the finish is especially important for visible windscreen repairs, as a smooth, clear result minimises distraction while driving and preserves the overall look of your glass. Subtle improvements make a significant difference to safety and appearance.
