[redmodelt]

I make my own slip plate, rustolium and powered graphite. I paint on the under side of only the contact area of the spring, assemble then paint the whole spring. I just add the graphite till I think the pint can has enough and maybe a bit more. When it drys, looks gray like someone has rubbed it with a pencil. I got idea when reading how Ford make the same stuff in the Model T era.
