I basically wipe them off any chance I get. They always have seal marks up and down them but im not sure if its an abnormal amount. They are a brand new set of sr suntour raidon air forks. Is it normal for any fork to have black marks all over the stanchions from what I assume to be the seal?

When you stop seeing them is when I would start to worry. That would likely indicate that the lubricant under the dust seals is gone. The black marks are lubricant right? Probably mixed with a bit of dirt?

I wipe my fork even during my ride. I don't trust the seals to keep all of the dust totally out. Don't need the bath oil turning into sludge. Figure this justifies going longer between service.

By black marks, you mean something like this, right? (images owned by bikerumor.com)

To me that looks excessive...almost looks like a blown seal, or maybe the Formula's allow alot of blow by....
