Caliper slide lube?

Sil-Glyde at any metal to rubber contact points, brake grease on brackets behind any abutment/way shims after removing rust, caliper/brake grease on the very edges of
the pad backing plates where they make contact & the contact face at the piston if it is steel. On the Mopar slider faces, polishing the surface & using something to just
inhibit corrosion is best........................there are zinc sprays, rust prevention magic, etc., or just wipe the surface w/caliper grease, then rub off the surface coat.
