Mate, I know difference between Ra-4 and C41. Still have some C41 in the fridge, I've brought with me from Sydney 2 years ago but shooting color negative pretty rarely, so, they have survived. Recently, means couple of weeks ago. Maybe 3 weeks. It was on bottom shelf, where they keep B&W developers next to the fridges.
BTW, have anyone asked them if they'll bring chemicals on request for order? I'd love to shoot some 4x5 slides but no one developes them in Singapore anymore. I kknow we can order it from B&H and others but would be nice to have local supplier
