    Stabilizer will work for all color films - E6 and C41 alike and of all ages. Final rinse will only work with specific films from a certain date onward and will only work with the process it is intended for.

    What type of final rinse should I look for? I have several types of color negative films, in and out of date, from three manufacturers. However, only Tetenal's chemicals are readily available over here in Croatia, and they're very affordable.

    With films earlier than about 2000, you must use a formalin based stabilizer. Since we don't know what the actual cutoff date is, and we don't know which manufacturers changed over their film chemistry, it is always safe to use a formalin based stabilizer.

    Although there isn't much information about this stabilizer, let alone an MSDS, could it work well just based on this short description:

    It says low formaldehyde content. Well, it might be too low. IDK. Sorry.

    You need 3 - 10 ml / liter of 38% formalin to do the job right with E6 or old C41 films. If it is below 3 ml/l then it can become ineffective.

    PE, how to minimize streaks and uneven processing with a Jobo 3010 drum? A processor is out of the question for now, which means careful hand-rolling a preheated drum is what I can pull off. Can the C-41 developer be diluted slightly? Also, is it possible to over-bleach films?

    I can't help you with streaks except to suggest a prewet of the film in the tank and use extra developer. Just a guess. Do not dilute it. Also use a stop after the developer of 1 - 2% Acetic Acid.

    The bleach step goes to completion.

    Prewet, 1' to 2' at 100F/37,8C Several changes of water (2 - 4)
    Develop as recommended
    Bleach
    wash
    Fix
    Wash
    Stabilizer / final rinse
    Same setup in my Jobo CPA-2 with elevator.
    I start with a 2 minutes pre-wet
    Then the 3:15 minutes C41 developer
    a quick rinse
    4:00 minutes Bleach
    a quick rinse
    6:00 minutes Fix
    wash the film 1-2-4 minutes water change
    Outside the Jobo due to foam contamination,
    1 minute stabilizer
    drying.

    I am using the Rollei Digibase C41 chemicals but in fact it's a small re-filled Fuji Hunt C41 kit.
    It's containing C41 part A-B-C + starter
    Bleach
    Fixer
    and a Stabilizer
    Some syringes for measuring out.

    The (new) instruction manual is pretty clear how to handle it.

    Best regards,
