I peeled the blue plastic off the right horizontal stabilizer skin so I could match drill it to the ribs. To match drill the holes, you first put temporary fasteners (clecos) in the every other computer punched hole, and then final drill the holes to size (they're slightly undersized on purpose) and then swap the clecos to finish the rest of the holes. This makes the alignment very accurate.
You can see the reflection of the raised garage door on the skin. Some builders leave their aircraft unpainted and polish them to a very high gloss but they say it's a lot of work to keep them looking good. I plan on painting but the bare metal look is tempting. Reminds me of a World War II fighter.
