of cause, not) that's just a reticulation effect: pouring film tank with cold and then with hot (not more than 40C) water several times. At the end it was poured with water + 1/2 tea spoon of sodium+citric acid. Than I dried the tank in sun. So these spots could be also resulted from sweat appeared on a film during drying.

Interesting... Going to try, did you let it hang between the hot and cold water or just did it one right after the other...

the faster the better. reticulation is caused by sudden temperature changes. without redscale you could have such results as I had here [link]
