Can't be sure but that seems a little thin, I'd use .060 inch, but definitely buy a few different thicknesses just in case. It's pretty cheap and you can even buy them in variety packs of different thicknesses. The montana spray paint has held up quite well. I gave all the hands a light sanding with 600 grit to help the paint stick. You just need to make sure that you don't have directly touching/rubbing plastics during transformation. If you do, do some extra sanding around the area to be sure you have clearance for the hand (and a bit of paint) to fold away when you go to alt mode. To be honest I put off finishing Longhaul and Mixmaster because, with the momentum of 3rd party stuff, I was sure I super G1 toon accurate set of constructicons was going to come out- like any day. And now somehow, it's been years and that still hasn't happened! (Sorry the Toyworld set is not close enough for me). Maybe Fanstoys will get around to it, but probably not for a few more years. And I've learned to stop counting on Takara these days. So, maybe I should just finish the last two haha.
