We adopted an adult corn that had never been handled and for six months or so i got musked on everytime i tried handling him.
I just worked through it, i wore full waterproofs (easy to wash off) and placed newspaper over the carpet outside his viv so that as soon as the musk started flying it was "contained".
I started off holding him for 3 minutes and then over six months moved it up to 10 minutes. Toward the end of this time he started to musk less and less and after the 6 months he has never musked since.
One rule i did enforce was that noone else was allowed in the room and/or to try to interact with him just to get him used to one person at a time. After the six months i got him out of the viv and then passed him to my wife and he kinda freaked out but there was no musking, after a week of this she could get him out and there were no issues.
