Finished dimpled the left & right elevator skins and the remainder of the stiffeners. The skins are done mostly with the C-frame dimpler, but the folded trailing edge makes it tough to get to the last few trailing edge rivets. For these I used the pop-rivet dimpler tool from Avery. The dimples came out very nice, and comparable to the c-frame dimples (this is .020" skin...)
I also prepped the parts for priming by cleaning, scuffing up with a fine scotchbrite pad, and then cleaning again with acetone to remove all oils, inks, fingerprints, etc.
