I was printing from some negs taken back in the mid 1970s. Some of them are quite badly scratched. I was wondering whether a treatment for scratched negs is still available? I recall seeing a product called REPOLISAN (made by Tetenal??) for this purpose. It appears that it is no longer available, leastways not in the UK. Does anyone one else market such a product, or is there a formula for the same? Many thanks, BLIGHTY
