Following up on a couple of things:
StormScope had intermittent errors with antenna so I check the connector end -- found the issue with the pins. Corrected those and she is working fine now!
Also, the rivets seeping. The RV folks have a process to seal those up so I'm following that guide.
Remove the wing walk in my case to get access to the rivets (CitriStrip).
Clean area after scraping all the old wing walk off:
MEK, RED ScotchBright
Then Alumiprep and Alodine to prepare the surface.
The RV guys have a kit to do this so, to support a fellow builder, I order the kit. I'm using Permatex #3 aviation and I'll dilute it with some denatured alcohol to thin it a bit (this will help it seep into the rivets better).
Tank is low on fuel so I don't expect any issues.
Will be applying that over the weekend -- I'll take more pics.
I know -- why not do all of the wing walk? I want to be sure this rivet approach works before I do that. I'll patch it in the mean time with 3M tape and fly it a bit before taking on that full project.
