Hehe I don't Co ordinate much as everyone left my area !
There's a company somewhere down south that does a proper job, they take your car for a couple of days steam clean the underside dry and apply etc. It's not cheap about 500 ! But it lasts and is a worthwhile investment, whoever did mine did such a good job that the 1st time my mechanic looked under it he commented on how well it's held up and looks rust free.
I had mine mapped as it was over fueling due to running on lower octane, i'm now getting alot more mpg 40 quid got me 250 miles this weekend of hard driving, before map it would have got halft the mileage , also slight increase in power and lots more torque.
