yukon,
I, too, like BoreTech Eliminator and use it as my first line cleaner. I have never tried their C4 carbon remover.
Fred,
Sounds like that would work. Leaving it in may be the secret. The white patch tells nothing. I use a Hawkeye borescope which tells everything. Hopefully the Dyne Tek bore coat will solve some of the problem, especially with copper. Carbon isn't talked about as much, but IMHO, is just as important, maybe more so.
Woodstalker,
Are you concerned about those products damaging the bore, or being corrosive? I don't know that they are, but don't know that they aren't.
Thanks guys for that info. Exactly what I was looking for.
DF
