My buddy finally received his Garmin GDL 82 and we are trying to figure out a spot for the GPS antenna and a ground plane. About the only available location at this point would be the top of the engine cowling where we could get a ground plane underneath the top cowling. Its not an RV and is all composite COZY MKIV. Pretty sure I read about a spray-able metallic conductive material for this purpose here on the forum a couple years ago, but no joy finding it now. May be of interest for me also on the RV-9A build, as I am trying to keep as much drag to minimum in my build. I remember a spray-able conductive material sold by AS&S for this purpose, but can not seem to find it on their website now. It may have been something like this? https://www.amazon.com/MG-Chemicals-Conductive-Coating-Improved/dp/B01N3AWGNX/ref=dp_ob_title_def
