I have sprayed a few of my bags with leather protectant ( I won't say which one because I don't want to re-start the whole debate ). I have some new mono bags as well that I have purchased and haven't used yet and I'm trying to decide whether I need to spray them or not. On one hand, I am kind of worried about putting all those harsh chemicals on the bags that I'll be touching and handling. On the other hand, I dont' like water stains. I wanted to know your experiences about water stains on the vachetta. Have you gotten them on your non-sprayed items? Does spraying guarantee no water stains? Will I envitably get water stains if I don't spray or I'll be ok? Please help me decide.
