Great question. For bonding wood to metal we would suggest our MAS FLAG Resin with our Medium Hardener and thickened with Colloidal silica. When bonding to metal, the surface must be bright and free of oxidation. Some metals can tarnish quickly so it is a good practice to apply the epoxy shortly after prepping the surface. Degreasing the surface with acetone, abrading with 80 grit sandpaper and degreasing again with acetone before applying epoxy is the simplest method to improve the epoxy to metal bond strength. Degreasing is a very important step and should be done even if the surface appears clean.
