OK, so an update I managed to get a hold of a 5L can of Kano Labs Aerokroil. It cost £35 shipping £55 and HMRC charged £40 for import and VAT duties, (thieves)! Parcel force held up the shipment for 3 weeks. It took 2 days for the USA end to send it and took 3 weeks from Stanstead Airport to Coventry Customs!
But this is by far the best read made stuff! I did email a company in the USA called Maltby Chemicals who produce but they couldn't even be bothered to reply!
Himanshu got a reaction from Ollie in Best Penetrant Spray.
