honestly - if a car is so delicate that it is messed up by suntan lotion...............you may have got the wrong car.
Unfortunately (or fortunately) since H&S, and the environmentalists got involved in car manufacturing, no car is safe.
Modern paints are water based. Older cars used Nitro-cellulose or Isocyanate paints. As Green1 said anything acidic or alkaline will damage paint. Sunscreen, bugs, bird poo even some older car shampoo will over time 'eat' into your nice shiny car.
So I'm not gonna put suntan lotion on my kids

Let 'em burn!

No. Go for the kids. Get the little b****rs locked up. The cycle of disrespect for law and order cannot be broken if you don't target the younger generation. Failing that go for damamges from the parents!
It wasn't intentional, If the adults didn't know, how should they. Years ago it wasn't a problem.
This is why I don't wash my car
My main issue is the cost of repairs or the potential drop in worth of what is, for most, a large investment. Apart from a house it's the largest investment. And I don't go driving my house around the roads 3 inches from other cars. That said I don't live in my car.
