ok this might not get taken on, but, i reckon applying pig oil and sulphur powder should be taken up as an olympic sport!!
i went to the yard this morning to put marys piggy stuff on and the midges were out, big time!!
she isnt the best one to stand still while i do her front legs anyway coz behind her knees are still scabby. im sure she could have gone in for a dancing competition and won
trying to dodge the front legs shooting up so i didnt get my hand squashed between a stomach and a hoof!! having the oil kicked all over the place so i ended up yellow too 
then having to dodge the strong thrashing tail coz of the midges and getting lashed in the face
but, i did it, she has oily, yellow legs and is sorted for a few more weeks
