50, hang in there! There is a convention this weekend and the OLD CODGER (boggy) and the VERY OLD codger RdFx are probably out tryin to catch trappers :cry: I'm pretty sure that one of those two will have your answer.
I only ever speed dip. I don't understand the use of Muratic acid to remove the dip; Its been my experience that the acid only hits the exposed metal. Any place the dip is bonded stays dipped. You can wax over dipped traps. Just boil them in soap, lye or in some other way clean them before waxing. I just don't know what is, or why it is, flacking off for you.
