is vernis bad for summer??

It says in the LV site that you sould avoid direct sources of heat and direct sunlight. Also some tpf'ers mentioned that some pretty bad untreatable marks appeared when vernis was left in the sun with drops of water on it.
 
it depends on how often you use it i suppose? I had a Chanel white patent bag i used ONLY ONCE and it turned yellow on me:censor: ! But then if it's only wallet which is not directly under the sizzling sun, it should do fine :flowers:
