FAQs
1. How long does DIY windshield repair last?
DIY windshield crack repair typically lasts 6-12 months before needing professional attention, compared to permanent solutions from a mobile windshield repair service.
2. Can I use super glue for windshield chips?
Never use super glue – it creates haze and makes professional cracked windshield fixing impossible. Only use resins specifically designed for auto glass.
