I finally got to the point where I wanted to get an IFR certification done for my RV7 and took it to a local avionics shop. Everything was great. They took my altimeter up to 30k and it did fine. Transponder checked out fine. Everything was great ... except ... right -at- my static ports there was a leak. They have worked to seal that leak and are having no luck. I'm reaching out to the collected wisdom on the forum here for suggestions.
I am using the standard Van's pop rivet static ports. We have tried RTVing the tubing to the stem of the pop rivet, and it seals fine on the inside of the fuselage skin but leaks under the -head- of the rivet on the outside of the skin.
I believe I have heard people say they have nested smaller tubing inside the larger tubing to get a better fit on the shank of the pop rivet, but am having trouble finding any reference to that. I have read the following thread :

It is good information but we are somehow not quite getting a successful outcome. Any additional information would be welcome. The avionics shop does have an experienced RV builder who helps them part-time and he is being consulted about what -he- did, so maybe we'll have an answer soon anyway. But in case someone had meaningful insights I wanted to float the question. Thanks!
