Sure, give it a shot!

Reindeer are the only deer where the male and female both grow antlers, so it could help.

But… antlers fall off and regrow the next year, so you’d have to keep repainting…

Also, when the males rut, they tend to scrape their antlers on trees, so that’s probably not good for keeping paint on the antlers. Bonus! Finnish drivers will likely be able to see reflective trees and avoid them!
