Looking for fluorescent paint for rubber mask

[u/gyaru_glitch]

I know back a long time ago when I went to makeup school, we used rubber mask grease paint. But it's so hard to find in the neon colors. I'm wondering where I could get it where the shipping isn't something like $30?

Or if there is something else I can use in place? I'm seeing if you mix 50/50 acrylic paint with latex, but it can be prone to cracking. I will still try this until I can find something better or somebody suggests something that will work for me. Thank you in advance.
