List Does Protek have a shelf life? I've had a big bottle for about 3 or 4 years. The last time I poured some into my hypo oiler bottle I noticed some "flakes" floating around in the liquid. I know of no foreign substances that could have gotten into the bottle, so the flakes must come from the Protek. They're small, and perhaps a bit whiter in color than the liquid. I call them "flakes" because they're shaped like little corn flakes; flat and irregularly shaped. They don't seem stiff, but flexible and diaphanous. I have to say that the liquid in the new bottle of Protek (the old one is almost empty) is clearer in color than from the old bottle. The Protek in the old bottle is yellower. It still works, though. I've used it recently with the usual great results. Anybody ever see something like this? Tom Sivak Chicago -------------- next part -------------- An HTML attachment was scrubbed...
