I'll stick my 2 cents in too about POR15. I did my rear axle, front suspension, etc with POR Black. I was told to put on new clean surfaces a "Surface Prepare" spray which smelled like an acid wash. I was told that you have to prepare new clean sufaces foe the POR to stick. It worked great and I have used it over rusted pieces just wire brushed and it's amazing! It's better that powder coating in some instances!
