I was on the phone yesterday with NYC regarding my BB Kelly (the scratch became better after a Meltonian treatment but there is still a problem area), I was then asking as I have a bag that has sort of an oil smudge inside... I was told they do not work on the inside of the bag..... I was a bit surprised to learn this... Claude said I could send it in anyway and he would have a look at it... But what do you do when something happens inside your bag ? anyone any experiences?
