Hey all i just recently purchased one of XDMRAY's awesome half masks!!! Unfourtanetly I have a huge dome. The foam maintaing the mask is causing pressure points all over my head and causing me bad headaches when i put it on. I was wondering what i should use to remove the excessive foam in the mask. Right now im cutting it with a exacto knife was wondering if any of yall had a better idea on how to cut the excessive foam out and to make sure i keep the areas nice and smooth etc etc? Any help would be awesome thanks. Karl
