So I took a real hard look at those beautiful, gold anodized RV-7 spars this morning and noticed something that made me scratch my head. In one section of the spar web, there are all these teeny-tiny little pits. At first I thought it was just some really fine dust but I can't remove it by rubbing with my nail.
I've heard that corrosion can start out as tiny pits like this, but I've never seen it first hand and don't know what to make of it. I find it hard to believe that I would have any corrosion at all given that the spars are less than a year old, they're annodized, and they've spent their whole life sitting in dessert weather.
On the other hand, I don't know what else it could be. Has anyone had a similar experience on their spars? I'm going to try to get my tech counselor over to look at it this morning but I'm curious if others have found anything similar and maybe can shed some light on this.
Here's a picture. Quality isn't great but it's the best I could do.
