When I did Ford Fair in the Series 1 a couple of years back I found it was the little things that counted the most
Things like clean the pedals and the foot mats, be really thorough, I know your driving from Ireland but if you want to stand a chance then your going to have to mask up the front of the car and clean as much as possible still to even stand a chance!
Wheel arches are another one and the inside of the wheels, just things that you wouldn't clean on a normal quick wash, just go the extra mile
I'll come and say hi as hopefully i'm going to be at FF again this year
