If you are one of those people who are plagued by an repeated assault from bird crap, and you use paste or cream wax to protect it, You're making more work for yourself.
Wax has absoutly no defense. against Birds.
Bird droppings contain a natural digestive acid that eats into wax.
It does not have the same effect on anything else just wax.

Bird droppngs have no effect on VaporWax, it isan acrylic paint condtioner. it does not contain any form of natural wax. Clear water and a quick wipe is all it takes to remove all traces of bird crap.

There are no etch marks, nothing to indicate bird crap had eve touched the car, no matter how long it sits or how hot the sun.
