/cgl/ - Cosplay & EGL

I'm so happy I can ask you guys and not try and blunder on LJ fursuit comms.

I'm making myself a werewolf partial for Halloween using a blank resin head my friend made. I'm leaving the muzzle/face/forehead unfurred to give it that hairless face look. For whatever reason I was thinking, is it safe to paint it with acrylics? Especially on the inside of the resin (I just wanted to paint inside the mouth dark pink so it wouldn't look weird if I can get the jaw to move with my chin) where I'm worried about fumes.
And I feel like I've heard someone say before not to use hot glue because of fumes, because I need to glue the teeth in there, but I could be completely mistaken and mixing it up with another type of adhesive.

Since I'm only going to be putting fur on the outside of the face and the neck, can I just hot glue it straight into the mask? I haven't had luck finding any picture tutorials about attaching fur to a resin mask.
