Even some places that just fix chips but don't replace windshields do grouse about Rain-X. However, it's easy to remove Rain-X if they really want to do the job rather than complain about the job. Rain-X's own X-Treme Clean glass cleaner will remove Rain-X, along with most other contaminants, very easily.
