Decided I couldn't do any harm to just deburr the rear HS spar and doubler. That sucker is long.

When removing the blueing, I noticed my hands a bit sticky and then I could see some fluid on the surface of the vinyl. It almost felt oily, but then was definitely a little sticky. When I pulled the blueing off there were areas where it had run underneath and had eaten into the alclad. I think was able to mostly scuff it out and since I'm priming anyways it is probably not a problem. I'll send a picture to Van's.
