For the recent  builders: I visited Copperstate and admired a 10 there. We discussed his paint  job and looked at the fiberglass areas after 60 hours. The external rivet lines  that result from the cowling hinges and lid attachment to the aluminum were  beginning to show rivet heads through the paint. This will occur unless the  aircraft has a layer of Eglass over the rivet line. Ask me how I know; I missed  the few rivets around the oil door on my Glastar. He also has an indentation  beginning to show were the windows meet the flange of the lid. Both problems can  be avoided by glassing a 1 inch wide strip on a 45 degree bias around the edges  of the window flange and over the rivet lines in the cowl. The Eglass is then  covered with a thin coat of Evercoat finishing, sanded smooth and feathered into  the adjacent structure.

David, you have a good eye on the emerging trend.  As you might remember from about a year past, I had posted pictures of cracks which developed in fillets from the use of microballoon.  I also showed pictures of recesses in poly filler which takes 18 to 24 months to reach mature cure.  That can really hurt when you lay a three color, custom paint job over those fasteners. Your post on the use of a layer of Eglass was picked up by Deems in his build.  I am confident that time will prove the wisdom of the technique.  

   

I think many following the build it by the instructions from VANS will find that skills of Sheetmetal and rivet building have to change as the composite parts count and techniques need to be adapted to those with skill at plastic planes.  

   

It was too bad that only N110GS made it to Copperstate.  I did enjoy seeing it as well as Jon Sharp’s NXT, the Spooky C-47 and a new Light Sport offering though.  94 degrees in late October – Wow.  Back to the rain and the Pacific NW humidity patterns.
