Brazing, need advise to fill a ding

[CNC Dan]

. A reducing flame has less O2 than stoichiometric.

A slightly reducing or carburizing flame is preferred for most welding because an oxidizing flame tends to oxidize the weld material due to the high temperatures and the excess oxygen in the flame.

You are right. I was corrected in an earlier post by someone else as well.

I wonder if JB weld or some other epoxy would work if it would adhere?

I wouldn't worry about filling it, just dressing it down so that no sharps were cutting the seal. It's not like there will be any leakage, just whatever minute amount of fluid gets scuppered out in the crater. A bigger concern would be the possibility of rust forming in the breached chrome plating. Maybe cleaning with acetone and a stiff brush, like a trimmed back toothbrush would be sufficient for epoxy filler.

Or leave the leg up so the ding is inside. No rust that way.
