I will let the flies clean it and then soak it in your choice of whitening products and then leave it bare. I think the clear coat takes away from the look of a well done skull mount. I have done all of my own mounts with maggots and bleach. I only soak it for about an hour or so. Sometimes I have to boil it for a bit to get the grease and slim out of it, agai only an hour or so. Have employed the power washer a time or two also. I do have a mt. lion skull that was done with bugs from a pro, then it was placed in a whitening solution(hy,Peroxide). very well done, but for the budget minded guy who can get a bucket of water and some baby flies in action you can do a real nice job. TBlll should set your teeth back in place just fine.
Enjoy! it is fun, Chuck
