Well it's been A week.
Tore him back down for skins and leg painting.
Snaps on an A&A frame... Not great.
The top ones under the upper ring are a lost cause. No room there for mounting the receivers. At all.
The ones for under the shoulder area are a little better, but not much. There was just enough room for ONE screw. So I got some 1.25" 4-40's and screwed them down as far as I can. I might try to add one or two at the sides since I have extras, but we'll see.
The lower snap receivers aren't a problem at all. The plastic frame doesn't do much for receiving the stock screws, but again, the 1.25" ones go down through it no problem with plenty of room for the nuts.  It's not as pretty as a metal frame with its own taps but the skins do stay on really well even without the upper snaps engaged.  If it starts slipping or anything, I can live with screws going in from the outside since they'll be covered by the top of the shoulder anyway.

Not happy with the paint so far.
The middle leg has had problems. Mostly related to using the wrong glue to stick on the styrene covers.
I used testor's model cement... Apparently this warps the styrene to the point that bondo can't smooth out enough of that surface, so it makes a heck of a mess.
I re-cut some new styrene covers and stuck them on with super glue. They seem to be better. Today will tell that story.

The resin leg pieces seemed to take the  paint and primer pretty well.

I did get the utility arms in the mail and they are drying right now.
