The bluing on my .280's barrel was very thin, and the rag turned orange even the first time I wiped it down, straight out of the box. After one deer season (and two deer), I called NEF and asked if they'd reblue the barrel. They did, under warranty. Hunted with it just this morning and got caught in a heavy downpour. It was nearly 3 hours before I could wipe the rifle down with BreakFree-- no orange, the reblue from two years ago is still holding up great.
