Jon - I have that in the fluorescent yellow. Exact same stuff. But I find that it doesn't show up as well as the white. White Out correction paint works too but it doesn't hold up.
BTW your patch lube/bore polish worked nicely. My bore looks better than brand new.
BTW one more thing I forgot to mention regarding shooting this rifle. With the 39" barrel and me at 5'9" it seemed like I was going to need a step stool to load it! The longest barrel I've ever loaded previously was a couple of my 32" GM barrels on my Hawkens and Renegades.
