Engine Guard Install Question?

[jtopiso_imp]

Hi:

Let me resucitate this old thread to ask a question.

I have got the honda engine guards, and before I install them:

Do I need to put something to protect the frame, so original paint is not damaged by the engine guard, or is should be mounted directly, metal-to-metal?

My concern is to make some paint damage that could start some rusting.

Thanks!
