Selecting the right option
CRC lists CRC Prep It Anti-Corrosive High Build Easy Metal Primer 2114 - 400ml and CRC Zinc It among the coatings that can be applied over Etch It. For bare or lightly rusted steel, CRC lists CRC Prime It Anti-Corrosive Primer for Steel 2091 - 400ml, and says to pre-prime aluminium, stainless steel, brass, copper and galvanised metal with Etch It first.
Using it
CRC's surface preparation: remove signs of corrosion with a wire brush or emery paper or similar. Clean the surface with CRC Brakleen or similar degreaser if required. Where possible, abrade the surface with disc grinding, wire brush or sandpaper.
CRC's directions: shake the can until the agitator ball is moving freely, then for at least 1 further minute. Apply one thin coat with smooth even strokes to a clean, dry surface, holding the can approximately 25 cm from the surface.
When finished spraying, clean the valve by turning the can upside down and pressing the button until only pressure escapes. Clean up with acetone or lacquer thinner.
