I ran a ground wire from the front thru the same grommets as the tail light wire. I also added a ground wire which I screwed to the brace on the bottom rib of the rudder. Looks like I should have plenty of grounds in the rudder. The Aeroleds show to ground the tail light frame and to ground the braided shield as well. I shot a coat of sanding primer on the glass in the nose of the rudder cap—tons of pin holes! I sanded it down and applied a coat of resin. I used a credit card to squeegee the resin into the pin holes. After the resin was dry, I sanded again and then applied some Super FIl to build up a couple of areas.
