I know there is a treatment to restore some colour back into film, though not proven how long it will last, I'm too sure what this application is not would I be convinced until a collector well know and trusted to us tried it.
Are they saying a single application to a faded film will make it all better? 🤣.
Pro 8mm California have (according to their website) been going since 1972, perhaps they genuinely do have the answer, but how come no one knew this all these years?
