Greetings. I am getting ready to undercoat the underside of my Camaro and was wondering how I should go about doing it. I was planning on cleaning the surface and then just spraying the undercoat (I got 3M Undercoating) onto the metal. Is this the way to do it? I thought I remembered someone telling me to paint it first, then undercoat, but I am not sure. Help please!?!?!?! TIA
