I don't understand how this was going to work? Was the plan to paint every year them all every year? I am not very familiar with reindeer but don't they shed the antlers every year like whitetail? So for most of the year they don't have antlers or they are growing them and they are covered with a soft velvet and only harden and scrap off the velvet layer on tress right before breading season. They fight and breed then shed thier antlers. You would have a very short window after they scrape thier velvet to paint and it would only be good for a 3-5 months at most. Granted at least for whitetail most of the accidents happen during the breeding season (like humans, male deer can be pretty reckless when it comes time to mate)
