When i write the article and post it on our site i will post the link.
So far i have just done the pics. I used a paint brush, some autoglym engine bay cleaner. A sponge and lots of car shampoo. Took me good 4 or 5 hours to do the whole underbody and remove each wheel to do each arch.
I have a load of step by step picccys look out for the link to the article.
