Tonight I worked on making the wing tip extension prettier. It had an air bubble in the fibeglass on the very edge of extension along the top edge. I had some epoxy and some flox so I filled it in with the mixture. This area is non structural so I used west systems resin and slow hardener. I took this time to finish the countersinks that I had missed on the last day of work. Today was only an hour but since it has been so long since I did anything with composites it was a nice chang.
