Galaxy Direct Positive Developing Alternatives

[Pioneer]

I have been looking through the various threads related to Galaxy Direct Positive (reversal) paper. I have plenty of it to use but I have run out of their developing kits. I have looked in all the common places but have yet to find any to buy. It would appear that it has been discontinued.
Does anyone have a formula for mixing up an alternative so that I can continue using what I have?

Have a look in the archives for paper reversal recipes Dan.

Really you only need a bleach. If you don't mind handling dichromate then 5% potassium dichromate/5% sulfuric acid should be OK. The dilutions aren't supercritical.

Otherwise it's just developer needed and of course sodium sulfite for the clearing Bath after bleaching.

If dichromates aren't your thing, a permanganate bleach a la ilford film reversal recipe will work, but might be a bit of a stain risk. You'll need a metabisulfite clearing Bath for that.
