When I euro mount velvet critters I just wrap the horns with saranwrap then foil and tape it all up boil the skull for 5 to 10 minutes then pressure wash it till there is no more meat exposed on it take all the stuff off the antlers and put 40% peroxide and magnesium phosphate mixed together and paint it on the skull dont get it on the antlers and let it dry and wire brush the chemical off the next day and its done the velvet looks good and stays that way forever, it just shrinks around the horns and sticks like glue.
