How do I apply Knockout Rust

Knockout rust may be sprayed, brushed or dipped, when spraying out of the aerosol can, the can should be held approximately 150 to 200 mil away from the work surface, as the product (unlike aerosol spay paint) mixes with propellant gas and will form bubbles if sprayed too close, when spraying keep on the move to avoid runs.

Do I need to prepare the intended area before applying

The surface area will take very little preparation, it is better to remove any flaking loose rust, as it is a waste of the product to make it penetrate all the way through loose rust, we use the slogan (THE PENETRATING RUST HUNTER) for very good reason, Knockout Rust will go strait to the core of existing oxidisation, starving the metal of oxygen and sealing the area from any further spread of rust.

How long will Knockout Rust Last

When using Knockout Rust for the original intended uses, inside car doors, sills, and partly enclosed areas of a motor vehicle and the likes, Knockout Rust would be expected to last the life of the vehicle, because of the tar content twenty years would not be out of order, when used on more exposed areas such as boat trailers and under mudguards where a lot of wear and tear occurs, obviously the life of the product will be shorter, depending on severity of abrasions.
