Before
So I repainted the skull with the rest of the house paint (I'm not squeamish about that, taxidermists may forgive me), and repainted the rods with potassium permanganate. You can get the stuff for a few cents in any pharmacy.
It is important to cover the whitewashed skull well with plastic bags, you can't get rid of it and the luminosity of these Kalium stains is considerable.
A teaspoonful of potassium mixed with water is overabundant and then the liquid is applied with a brush and one must be careful that no drops form on the trophy, which are wiped off with Kleenex.
