ALEXSEAL Surface Degreaser/Dewaxer is a wax and grease remover used to remove wax and other contaminates from gelcoat, painted surfaces and metal prior to priming. Grease and wax removal is important for new hulls, decks and components that have been released from a mold, or an older boat with considerable wax build-up. This initial removal prior to sanding can also be performed on metal to remove grease or other petroleum/paraffin contaminants.
