I’ve just acquired a quilted Rogue 25 in dusty rose — new in wrapping — and I can’t wait to use it. But I’m worried about color transfer and my kids’ greasy fingers, so I want to try and protect it if I can. (I usually carry black or brown bags and don’t worry too much about them.) I’ve read some recommendations for Collonil Carbon Pro, but also heard some people say that I shouldn’t put anything on Nappa leather. Does anyone have experience with this particular bag (or a similar one)? What do you recommend?
