Is it ok to use Fuji Bleach (Negacolor RA-bleach) and Kodak flexicolor fixer in C-41 process? Are they compatible? I'm having trouble finding small quantities of C-41 bleach in Portland, OR area and I can only get Fuji in reasonable amounts. So I've been thinking of using Kodak for the rest of the chemicals and Fuji for bleach. Is that a good idea or not? Has anybody done it? Thanks!
