Anyone thinking of buying the very attractive leather bonnet strap - a word of caution.
After one year on , I have found it harbours dust / grit underneath the leather panels behind the buckles , coupled with vibration from the works makes some pretty deep abrasions in the expensive top coat. Not normally visible - but now you know its there
I dont think you can eliminate this by its very nature - so I suggest unstrapping the belt whenever you give the car a wash and washing it out periodically.
