Make sure that the shop that puts the new windshild in doesn't use any metal tools during the install. Others here on the board have had issues with rust and water leakage after the shop installing the windshield used metal tools. The tools end up scraping the paint and zinc coating off of the metal then water gets in and starts the nasty rust process.

When I had my windshield replaced I made sure that the shop I went to used plastic and/or vinyl tools.
