This is Theodores 22B having some rally livery applied.
This work was carried out by Andrew Cliffe at Omicron Engineering. This is what Andrew had to say :

These decals are a real pain to apply. To get them to go on nicely, you have to wet the car, then attach the stickers in a such a way that they are not creased or have air bubbles, then with a squeegy or a spatula just press out the film of water and then the glue sticks them to the car. The big ones on the side are difficult, especially as the side of the car isn't flat, and the Subaru logo on the rear window is very thin and delicate.
