Caesar Mycaenaeans: Trying the Army Painter spray base

After my experience using Army Painter spray on the CMON undead hordes, which are a fairly hard resin, I have decided to try the same approach with Caesar Miniatures rather soft resin. So after a hot detergent wash, which (mostly) straightened out the minis, I sprayed one side, waited about an hour, then sprayed the other side. This is Desert Sand, a good leather/wood shade.

Not every piece straightened. The pikes, top left, are pretty bad. I can try once more, and if that doesn't work, I'll have to switch to wire.
