I used some will 91 isopropyl alcohol today in a dew small places (one before applying ppf in a small area, and another to clean a mark off my car.) Everything looks ok, but I didn't dilute it. Is there any chance I damaged the clear coat?
If you used gallons of it and rubbed away for hours then maybe. If you're really worried just dilute it a bit more with distilled water. A 25% solution of IPA will still clean off oil deposits but would have no chance of doing any harm to anything else.
