Carlos, thanks for bird-dogging Vic?s webinar for me. I?ve been reading his stuff in Kitplanes and he?s a great guy, very knowledgeable and willing to share what he knows. I?m a long-time A&P and among other things, I?ve been maintaining, preening and modifying our RV-6 and helping friends with their airplanes, including RVs for some years. I have seen some pretty incredible things on airplanes, too, and not just experimentals. The webinar was a great brush-up. As I said before, I?m not using RTV on the next air cleaner, for the same reasons Vic pointed out.
