I painted a Kaiyodo Shinobu Matsumura Tyrannosaurus soft vinyl figure. The process included: putty filling → priming with surfacer → painting with Tamiya acrylic paints → finishing with a top coat (UV cut protective coating). It can stand on its own for now, but the balance is poor, so it may fall over without support. (I've added material to the soles of the feet to adjust the center of gravity for balance.) This is a paint job by an amateur, so please understand this before purchasing!
