I haven\'t tackled any of the large AT-43 vehicles, but I did do a character :

In my case I acetoned it before repainting it. That was a bit extreme at first for the plastic (went soft, but hardened once dry).
The casting is OK, but not as good as the Confrontation metals or the AT-43 resins.
The major pain is getting rid of the mold lines since the plastic is \"gummy\". I found it easier to prime it, clean up the mold lines and reprime it. The primer seems to solidify the outer part of the plastic.
