I'm getting ready to install my DBA T3 rotors. After reading about the potential rust issues with the rotor hats I thought I would paint them before I put them on. Any suggestions on the correct paint to use. Thanks.
Try the POR-20 silver, hi temp paint. This brush-on paint will dry in 4-5 hours, and look like you spray painted them. You could paint directly over the rust, or wire brush/sand blast them before applying. I would avoid sand blasting the smooth rotor surface. You can buy it by the pint or quart; it can expensive in larger containers, but its worth it. I've had good success with this product after finding it at swap meets.
