Lots of work but not many photos today. Final-drilled the vertical stabilizer ribs and spars, dimpled, countersunk the spar doubler, scuffed the surfaces, cleaned with acetone, and primed with GBP-988 self-etching primer. This is not the absolute most robust primer that's available, but it's certainly one of the easiest to apply and it seems fairly durable. It's also on Van's official list of recommended primers, which must count for something. I also know that lots and lots of RV's are flying around out there with this stuff in 'em, and I don't think any have rusted out of the sky yet. I figure this airplane will last at least as long as I'm interested in flying it.
