I have had success using strips of 0.012 to 0.015 stainless, sourced from the hobby store, to protect between the clamp and the frame.
Leading edge tape is also known as "helicopter tape" if you want to search for sources.
I am starting to like the "green" masking tape over the blue masking tape for temporary use.
I don't care if anyone wants to get to 3100 posts or not.
