orange grease in caliper piston kit

The orange grease is a high temp grease to be used primarily on the caliper pins and holes, put some on the caliper anchor rails where the caliper and pads slide. Some people slop it all over the place only to have it wash onto the pads/rotors and ruin a perfect brake job. I've never seen it applied to the actual piston during a rebuild but you should call the dealer.....I've been wrong before on some of this new stuff.
