Okay , so my 55 gallon drum of Ultra Pure arrived the other day and I went ahead and washed my 1525 for the first time. Would you believe I found spiral metal shavings, okay, just one, in my bath? I was pleased when I discovered that, for I knew my horn was factory fresh. Thank You Tulsa.(PLUG) I Ultra Pured it when dry and I'm sold. ('Notha Plug) That "velvet smooth" action experience everyone mentions was all there. Also be it known, I'm using the compatible Ulra pure light and regular grease as well, because you already know how I am about compatible compounds.
