Thanks for the information. About the best solution I can find around here is to use an industrial grade stainless "shielded or lined" clamp. The shielded or lined clamps have an inner band to prevent damage to soft hose material.
I am disappointed to see the AACA specify on printed page 24 of the guideline manual (Engine article #1) that "All radiator and hose clamps must be as provided by the manufacturer." So if hose clamps become an AACA violation for the car someday, then I can regress to manufacturer style only for any visible radiator/heater hoses.

Also, I hope to use the Ultimate Garage ABA rubber sleve clamps for securing any wiring or lines to prevent direct contact with a metal surface.
