Eastwood Diamond Clear Satin/Metal Surfaces Aerosol 11 oz.
Product Review (submitted on April 11, 2011):
I have used this on bare metal to "seal" it in to avoid rust. It does a great job. The sheen was perfect so as it was not glossy. I sprayed it on my cast brake rotors and the cast master cylinder to add life to the part without it turning rusty. It went on smooth and I followed the directions to a T. I also used the clear for the painted surfaces with the same success as well..
