Can someone point me to Mule Deer's instructions on how to clean a barrel before using the Dyna Bore Coating?
Take into account most of the first responders are paid and not unbias.......
Assuming I understand your statement was a slam, have YOU actually tried UBC and do YOU have any input to the actual question besides speculation?
I have applied it to a few guns but have yet to see the advantage, but am holding onto my opinion until I can thoroughly make a positive statement.
I did send what I thought was a clean 17 remington back to Cooper due to poor performance and other issues needing fixed, and they scoped it and found copper I had not removed. With that, I can assume some of the guns I treated probably also were not spotless when UBC was applied.
