I was down 2 weeks ago to check on the RV4. While checking it out I noticed the same spot under the right wing that was there last year. It is located along the seam of the right fuel tank. Doesn't appear to be fuel leaking and can't smell any fuel and haven't lost any out of the tank. It almost looks like rust along the seam, it's black and brown in color. The spots haven't gotten any worse since last summer.

Can't seem to insert any pictures, but if anyone has an idea what it might be and how to fix it, I would appreciate it. Hard to make a judgement without photos so I will send them to you if I have your email address.

Appreciate the expertise out there.

Thanks.
