Bar wear question

[MS261CM]

OK, not exactly wear per se. This is the 18" Speedcut bar on my MS261C-M 3.0. The paint is chipped off both sides of the bar in a fairly identical manner.

Does this indicate:
*Too little oil? The rails look fine to me if I remove the chain to look.
*Too low or high tension?
*Normal as maybe the chain flings back to the bar in that spot? Don't worry/be happy?
*Funky spot in heat treatment? (Probably not both sides)

I may as well ask now before I run it a lot more.

Nothing to worry about, just keep cutting.

Pressure point and/or hot spot.

I'll do just that.

I did clean the groove and take another look. This is a bonded laminated bar. It looks like the manufacturer was a little sloppy with the laminating adhesive in that area. The chain seemed to feed ok but there was a bit of adhesive just behind this spot in the groove. I cleaned it out and re-assembled.

Normal for those Oregon bars, in my experience. Nothing to worry about. I believe it to be a poor paint process.
