Used a bunch of acetone, a little brush, and lots of paper towels to remove the remaining bits of Bondo glazing putty and the primer that stuck to the part.

Clamped to the workbench and ready to trim the flanges.

Had a few little voids / irregularities, so I mixed up some 5 minute epoxy and microballoons to fill those spots.

My new West Systems 105 / 206 kit came from Aircraft Spruce. Looks like someone kicked the resin can around a bit before shipping it. :-( At least it didn't leak.

Sanded all the areas I filled with micro earlier.
