I've heard that statement more than once. Thanks for the responses. I usually use a 35mm film can, the black one with a gray plastic cap. Insert a ball of cotton and put a few drops of Tinks on the cotton and snap the cap on. When I get in my stand I pop the tops off and toss the small cans out in a circle around my stand. Then pick them up when I'm done for the day. And they can be used they next day. Usually at a photo processing place they will give you all you want.
