just got done refinishing wood on a bl22 for grandson someday, he's only 2, was wondering if the metal in the barrel bands is an alloy or not, they were scratched up real bad i removed blue and tried to reblue but the blueing won't take it just wipes back off. been at it for 2 days. any suggestions on how to get the high gloss black finish back on them, they look bad next to new wood and the touched up barrel.
