FertanRust Killer/Remover/Treatment 5L Litre Corrosion Protector Remedy is perfect for Body Shop/General Work Shops/Classic Car Restorers/Commercial Vehicle Repairers/DIY Car Enthusiasts

I have used this product for a number of years and provided the instructions are followed, will provide protection for a long time. The underside of a rotary mower was treated after welding holes four years ago and so no rust has appeared.
