I streamlined the sequence a bit (same colors, just re-ordered some steps so I'm not going back to the same pots) and kept a stopwatch running while I painted - took about 12 hours to do the squad. A little math averages me an hour-and-a-half to an hour-and-forty-five per figure, depending on the type of squad.
Both of the "Breaching Squads" in my list are technically Plague Marines, and while I think the shields help denote the Toughness increase and Feel No Pain well enough for most folk, I thought I'd amp up the rust and patina to give 'em a metallic "decay" look, just to help drive the point home. It's not quite as pronounced as I thought it would be, but I'm happy with it.
While I had the wife's camera to snap nicer pics than last time, I brought the Zigouilliers back out to help see the difference...
I plan to take the rest of the month off from painting to work on building/converting the last Rhino, both Vindicators, and the Dreads. I'll also be working on some custom Iron Warrior Rhino doors/front plates for The Freebootaz annual Toys for Tots army. In March it'll be back to the painting table with... whatever vehicle or unit gets me a fully-painted Combat Patrol for Adepticon in April.
