Any experience with Super Fujifix-L?

[dogbunny]

It is an acid hardening fixer that I think is only available in Japan. I managed to find some data on it with google translate. The only thing that threw me was that it suggests hardening times of 5-10 minutes. Hmm...5 minutes? 7 minutes? 10 minutes?

Any suggestions on times, rinsing or anything to be cautious of while using it?

Thanks,
