This is a product that is far, far better than paint-type etch primers.
Metal-etch gel is a phosphoric acid based metal conditioner/cleaner. It is suitable for bare aluminium, galvanised iron and non ferrous alloys, brass, copper and bronze. You simply paint it on and rinse off thoroughly after about 20 minutes. Allow job to then dry completely.
You can then paint the surface with a standard metal primer, such as TQG342 and TQG344.
This product will give you the best possible preparation a metal surface can get. It can be clear lacquered as well.
Comes with all application instructions including safety handling etc.
