I got caught in a rain storm in November of 2011! Of course my stresa had water marks on all of the vachetta with the flap taking the worst abuse. I let my bag in the sun a bit then tucked her away hoping that with time and patina the water marks would get better and even out. Not the case. They look just as bad if not worse then ever. I need some advice on how to help this. Should I let it be ( I think it's ugly). Should I get LMB by Barbara? Try baby wipes? Help.
