Alcohol will not damage the clear coat no matter how much or how sunny. The clear coat is an urethane acrylic compound and most alcoholic or petroleum based products will not touch it once cured.
This is why bird crap will damage it so easily though since birds do not urinate separately and the waste uric acid from their system is mixed with their feces. Uric acid makes a great solvent for both urethane and acrylic. You also want to stay away from any products that include ammonia (i.e. Windex) since they are very rough on acrylic coatings.
So I guess ultimately you really should not piss on your car but most everything else is fine.
