Lens hood for Olympus 75mm 1.8

I use a JJC hood for the 12mm but its inner ring "seriously" scratch the smooth surface of the barrel.  For the 75mm, similar design, I had a friend who has the olympus original 75mm hood but still scratch the surface.  Although not serious but that should not happen for such an expensive lens and hoods combination.  I am still interested in the JJC hood, to avoid scratches on the body, I will put a tape around the contact surface.
