If this was a Marzocchi I would tell you to not worry about it, the seals are so tough, they'll polish the stanchion for ya.ATOMICned said:
If there is no oil coming out, you don't have to do anything. If you want, you can take some JB weld and fill in the scratch, then you will need to sand it, which I would personally be really nervous doing, since you run a risk of making things worse.
