I already have Shining Monkey but after hearing Sophia's reaction, I wanted to try the Wilson's. I did a search, I think it's ok to use, right? Any advice, any bad reactions, horror stories? Also, how many times do you spray this on it? I'm going to use it on my new bosphore pm which really doesn't have that much vachetta but still I don't want water stains like my other poor bags.
