I just used this for the first time today. What a great product! I found out that the various copper solvents I have historically used are nothing compared to this. I filled the bore, waited 12-15min (as per instructions) and ran patches through until they came out clean and dry. Got the copper out pretty quickly, and the bore looks better than it has since it was new. If you haven't tried it, you certainly should.
