Maybe you could use something like this?
I am using the graphite paint on my XJ pack.
Added main leaf to the pack. (no friction pad) only the one leaf. It does seem to work well but I would not do it, without the pads, thoughout the whole pack.
I also opened up the clamps to help the leafs fan out.
93 YJ SOA 2" springs front, XJ springs rear w/main leaf added, High pinon 9 inch rear detroit locker front Dana 44 ARB 4.56 Gears, 36 inch Irok tires too much to list. www.mijc.org
