Apparently!
Actually, I dunno how the stuff works. Doug Burche told me it filled in imperfections in the bore, but since it also apparently works on super-smooth bores.
Maybe it's like a Thermos bottle, which keeps cold stuff cold and hot stuff hot. :-)
DBC fills in the pores of the steel and has a lower coefficient of friction than steel, so once cured it "scrapes" less material off the bullet jacket, and as you know, it relinquishes it much easier than steel does, as well.
