Hi everyone, hope you can help me with this. I was told different things about spraying the vachetta (to protect from rain, stain, etc). The LV SA told me that I'd have to wait for the leather to turn tan first before spraying it. But on this forum, I hear of people spraying the vachetta when it's still brand new. What is correct? And what do you use to spray to protect the leather? Thank you.
