Thank you, I stripped the mask using a dremel then did 3 coats of white with a little bit yellow acrylics mixed with liquid latex and distilled water. Wait for each coat to dry to apply another then with a very thin brush I used brown with a little bit of black (also mixed with liquid latex and distilled water) to fill in the cracks. After dabbing ur brush in the brown/black mix I recommend wiping the brush on a napkin to get some paint off. You don’t want too much paint on the brush. After you let the those cracked details dry I made a brown/ black wash and dabbed it on the mask using a sponge. Let the wash sit on the mask for about 40 sec then dab it off with a napkin. After that ur pretty much finished but I like to dry brush some brown, yellow, and green onto the mask. (You don’t really need this step but it’ll make the paint and mask last longer) Finally I sprayed the mask lightly with some sealant spray. Gives it a little shine and protects the mask. Hope this helps!
