It can turn in to a mammoth job as i've just started mine thinking it was just a quick clean but once you start digging you find other area's that may as well be done whilst your under there making the job a lot bigger than originally thought.
I've seen work done by
COSSIECRAZY the escort Cosworth registrar - he's up in Stoke on trent though but his work seems good, i've seen a few car done by him
