Whats the best wax or paint sealant to protect against bird droppings?
This incident really drives home the point that on the topic of protection and that’s ANYTHING corrosive enough to harm or etch a modern clear coat paint is strong enough and/or corrosive enough to eat through and obliterate any micron thin layer of wax or paint sealant from any company. Think about it… the clear layer of paint is harder and thicker than the thin layer of whatever wax or paint sealant you apply, let dry and then wipe off your car’s paint to protect it. That’s why it’s so important to keep a bottle of spray detailer and some clean, soft microfiber polishing cloths behind the seat or in the trunk for emergencies because if you love your car and you actively maintain a show car finish, then bird droppings that land on your car’s paint are emergencies! Hope this helps explain how long it takes a bird dropping to etch your car’s paint.
