Priming with Powder - The legendary durability of powder-coated finishes is further enhanced with this epoxy based powder primer. If the utmost corrosion resistance and adhesion are important to you, you'll want to use this primer under every opaque powder we sell. (Not for use under our new line of High Temp Powders, or directly under translucent finishes.) For best results apply to clean bare metal and place in a preheated 400 degree F oven until flow out occurs. DO NOT cure beyond flow out as adhesion will be adversely affected. Remove from oven, cool, apply powder of choice and bake as normal.
