Homebrew PCBs

I've acquired a roll of liquidated Aqua-Mer PR photoresist film that I
intend to cut up into smaller quantities for sale on Ebay (toot! toot!).
My question: what is the correct developer?  I picked up a bottle from a
downtown shop that turned out to be a sodium hydroxide solution, which I'd
rather not mess with given that it's relatively unforgiving with
overdevelopment.
