>>103952731. I've dismantled many figures made from this plastic before and never had issues with the plastic being permanently stretched, boiling water or 30 seconds under a hair dryer is nowhere near the plastic's melting temperature so any deformation is temporary. Note: boiling water to soften it up for dismantling, hair dryer to soften it up for reassembly. If you submerge the figure in boiling water after it's painted you'll mess up the paint, and with a hair dryer you can focus on just one spot, such as the joint you're trying to reattach.
2. Primer might help, but I've never really used it, I use a finishing spray after I paint it to make sure it doesn't scratch (krylon matte finish to be specific)
3. This plastic isn't THAT rubbery, it's similar if not the same as the plastic used to make Marvel Legends figures. That said, the paint I've found works best is vallejo model color acrylics, as the name implies it's a paint meant to be used on model kits and works well on these figures (as long as you use a finish to make sure it doesn't scratch or peel afterward)
The Sally figure on the right was made using this Amy figure as a base and the paints I mentioned, just in case you wanted some context on how it looks.
