I have seen a bunch of wall mounts that look really shiney......are they polished with something or have a clear coat finish of some kind on them??

My dad said he put some clear coat of some of his antlers and it didn't do any damage.........some are 25+ years old.

Is there anything I should NOT use to shine them up a little?? I don't want to ruin any of my racks but some look kind of dull.


Thanks
