Important application note:

• Deep aluminium corrosion must be repaired before refinishing.

• Aerosol products may be restricted to ground transport.

  

🔌 Function

  

Zinc-phosphate primer promotes adhesion between bare metal and the colour topcoat while slowing under-film corrosion.

  

Common situations requiring primer:

  

• Paint chips expose bare aluminium

• Gearcase skeg has been repaired

• Corrosion has lifted the original coating

• Midsection or bracket has been sanded

• Welding or grinding has removed the factory finish

• Surface has been prepared for a complete repaint

  

Application considerations:

  

• Wash away salt and contamination

• Degrease the repair area

• Sand or mechanically remove loose oxidation

• Feather the edge of the existing paint

• Mask seals, anodes, shafts and machined surfaces

• Apply several light coats rather than one heavy coat

• Observe the flash and recoat times printed on the can

• Apply a compatible BRP or marine-engine topcoat

• Do not paint sacrificial anodes or grounding contact points

• Use appropriate gloves, eye protection and respiratory protection

• Apply only in a well-ventilated area away from ignition sources

  

📦 Condition

  

• Genuine BRP Evinrude Johnson OEM product

• Brand new aerosol primer
