Can anybody recomend a supplier. Think I normally pay about £35 off autosmart, could I do better ?
If you are struggling it’s the chemical that you put through a pressure washer 
Try your local motor factors who are IFA members mine had a great deal on Swarfega TFR so got loads! still got 2 drums sitting in the garage now
Thx for the info just ordered some off eBay cheap as chips will let you know how it goes
