Thank you very much, very informative (although I don´t actually use oils) and the pantjob itself is outstanding. For those who don´t know: This is Pater-Paladin Alexander Anderson from Hirano´s manga 'Hellsing'.
I bought around $300 worth of oils last spring and used them once (though the results were horrable!) maybe now with this article I can give them a bit more of a try.
