Most cars I've owned I've cleaned caliper using a wire brush attachment on a drill to removed all rust/corrision.
Paint them hammerite smooth (Silver or black), with a brush and get good results. I generally only keep my cars a year and they always look good in that time so have no doubt they will last. I also paint the hubs.
With the disk guards I wire brush them and spray paint them Hammerite Satin black for a factory look finish.
First time Ive used decals but as their under lacquer I can't see no reason why they won't last
