I've got a problem with my QB wings (and flaps and ailerons). I've etch primed my wings and noticed that several rivets (40+), as well as skin seams at the spar, leak what I believe is the preservative (anti-corrosion) put on the parts in order to avoid corrosion during the over water journey from the Philippines (where the QBs are pre-assembled) to Oregon . I've washed them with everything from MEK to Dawn/water through a high pressure washer and spray gun followed by a highpressure airgun (as recomended by Vans - to push the stuff back inside the seam). I've done this repeatedily (at least 20 times) and still have the preservative leaking through the etch primer. I've even got rivets in the gas tank leaking preservative through the primer. Does anyone have an solution? This has taken all the fun out of the process. The last thing I want is this stuff to leak through a final paint job. Very frustrating!
