Hi All, I just bought a relatively unused preowned horizontal Lockit bag, which has a significant amount of vachetta on the bottom. I wanted a lovely and durable bag for the upcoming trip to Hong Kong. I am leaving in three days. Unfortunately, I found out it will rain in HK during my trip. The vachetta is very light, and I am worried about water stains. Also, I want to have a little more worn in look to it. Typically, I just use leather lotion to darken vachetta a bit. But with such large vachetta area, I am worried about what is the best way to darken AND protect it. Dear Ladies, PLEASE give me your best advice. I bought this bag to make it into a trusty travel companion. Your advice is greatly appreciated!
