I want to put something on a non-threaded kingpin seat post to make it easier to put in and remove. Two things that I have on hand to use are powder graphite and liquid silicone.
I want to try the silicone first because I don't think it will be as messy. If I am not happy with that will the graphite still do the job putting it on top of the silicone or would I need to make sure I got rid of all residue first?
