A stone chipped the windscreen a few days ago and I wanted to ask a couple of questions before I get it fixed. 1. Is it a good idea to claim on one's car insurance to cover the cost of repair, or does this raise premiums or have other similar detrimental effect? I think my policy covers this but I need to check. 2. The chip seems fairly deep but it's only about the size of a 1p/5p coin. Any special advice? 3. Which is the best repair company for a quality, lasting repair?
