    manitou minute fork stanchions internnal scratch

    Greetings every body

    Sorry if am posting in the wrong thread please advice.

    I own a manitou minute comp 29er fork the version with the black stanchions, it was working find, All of a sudden it started leaking air to the lowers and loosing pressure.

    Changed a couple of air piston thinking that i was the problem no joy continues to lose pressure after 2 rides exactly maximum three, after closer inspection i first found the air piston seal to have abrasion marks on a certain point on all piston seals i used the one that was already in when it started loosing air and the following 2.

    After further inspection i found that those piston seal marks are corresponding to internal stanchions scratch.

    1st question: what could be the possible cause that would lead to development of such scratch?

    2nd how to avoid in the future cause i have the same exact fork on another bike ?

    3rd is there a way that i could polish or smooth out those scratches i believe if i did so that would solve the problem

    attached photos of the scratch, fork and piston.

    much obliged

    If the material is missing, (as what a scratch is), polishing would only remove more . That may be toast.

    Actually it doesnt matter cause in my situation i managed to fit a little bit larger seal around the piston in another fork and it seems to work all i need is an idea which would help to smooth out those scratches cause every time i try to install a new seal those scratches ruins it.
