I'm sort of newbie, and I have question about TW25B.
I got small sample tube of TW25B a few months ago with my new Sig P239. I like it very much, and as I used all of it I ordered big 4 Oz tube of TW25B by Mil-comm from midwestguns. To my surprise this stuff I bought from midwestguns is way different. Here are the differences:
small sample tube: the grease is white, it is grease, i.e. you apply it and it stays there, though easily spread. Just like what you will expect of good grease.
big 4 Oz tube bought from midwestguns: it looks more like oil, semi-transparent, it leaks like viscous oil. I did shake the tube, and it made the content closer to the sample, more white, and just somewhere between oil and grease. When I used it after a couple of weeks again without shaking tube, it is again more like oil.
Which of these two TW25B is good which is bad? Or they both are OK, and this is a sort of difference you can expect? I doubt it as I can't imagine military folks who are using this stuff will tolerate variance in properties like that.
I found the following on the rare end of the big tube: "WG 102809". If this is decoded as packing date (which may not be the fact), the stuff was about a year old when I bought it. Knowing a bit of chemistry I doubt it will deteriorate in sealed container to change its properties to that extent.
Could someone solve this puzzle for me? I was so happy Sig sent that sample of TW25B grease with the pistol: it was so good...
Thanks in advance for your answers.
