Honestly, I'm QUITE amazed. I have a roll from our trip to Mexico where sand must have got on the felt (of the 35mm cartridge) and put several pretty deep and long scratch. All of those frames with scratches printed *just* fine.
I am getting a bottle of Edwal's No-Scratch just in case I run out of my nose oil. My understanding is that these oil needs to be cleaned off the film each and every time. There isn't anything that will stay on the film permanently to fill those gouges, is there?
