It might interest you that I have in my possession fiber prints produced more than 120 years ago that show little deterioration, and I'm sure the methods used when they were produced were not so strict as today.

The so called experts of today must wait that long to prove their claims. I don't believe everything I read unless the person has a good track record of providing sound information, and I surely don't trust that all new products are better than what came before, regardless of what someone else believes. I know I sound like a cynic, but I have my reasons and I've been around for a long time - more than half a century.
