Alright ladies and gents! This resource has been awesome, I'm still a newbie but gaining confidence. I'll post some pictures of the two I'm currently working on and the next project (mummified deer skull). Anyways, I'll get to the point. I only do skulls for myself, family and friends. Even for them I want to guareentee a job well done. What's your process for taking a skull that has been "degreased", whitened, and sealed with paraloid b-72 that after time,starts to yellow or have grease surface? This can even be hypothetical. I know many of you are damn good and never have anything come back. Many thanks, have a great night and stay safe!!
