Godzilla Mask literally melting down! Help!!!

Well 8 years ago at G-FEST 2000, I picked up this awesome Burning Godzilla mask which is made out of rubber. Well, just like the rubber suits, the mask started decaying about 2 years ago. I did some online searching and asked some art stores and they said the best way to preserve the rubber would be to seal it with a sealant. Now I did the exterior of the mask but didn't think to do the insides.... But I did fill the mask with tissue paper preventing the rubber from contacting itself and kept the mask in an plastic bag to prevent it from oxidizing but the other day I saw it and it didn't look like it was doing that well. So I started to add some more sealant in the inside and not sure if it's helping or making it worse..... Here are some pics. The thing is melting away just like the movie.... I don't know if there's anyone/place out there that I can send the mask to have it repaired...... Kaijuzoo maybe?
