Would like to know the significance of the last letter "C". Can Ardrox 9PR50A be used in place of Ardrox 9PR50C? In general, do we necessarily have to stick to the same combination of cleaner/penetrant/developper or can we bring some slight changes, for instance, when Ardrox970P25 is not available at hand, could Ardrox970P25E do? The context is NDT (crack detection) in aircraft maintenance (a bit strict). Thanks for sharing your knowledge and experience.
