I started work on my rudder assembly today and while I was preparing to final drill the rudder horn I noticed some surface rust inside the tube of the assembly. I know Van's directs priming any steel parts that aren't already painted, though I was surprised to find on close inspection the small unpainted area in this part and the rust. (I've only had it a 3 weeks.) It doesn't seem like a big issue now, but I'm wondering how all of you would handle it? (I also fired off a note to Van's.) I'm thinking applying a rust converting primer followed by a rust inhibitor both from a rattle can. I've attached a couple of pictures from either end of the tube.
Thanks!
Thanks!
