TotalBoat Halcyon varnish is suitable for direct application on metal surfaces following proper preparation.

Prior to application, ensure the metal surface is thoroughly cleaned, dried, and devoid of any grease, oils, or waxes. Use 220- or 320-grit sandpaper to sand the metal and remove any sanding residue. In the case of rust or oxidation, it is crucial to apply TotalBoat Halcyon within one hour of sanding, following the product instructions.
