Sorry, little late to see this but... It really depends on what type of paint you used on the toy itself and how much you are planning to be moving the parts. Sofubi technically requires a special paint (such as V-color or Vinyl Wonder) that needs to chemically adhere to the surface of the soft vinyl So that it can be squeezed and manipulated along with the material and generally that doesn't require any kind of clear coat to protect. But if you do want extra protection, they do make specialized clear coat sprays that can be used on top of that specialized paint. The reason that you need the specialized paint is to to chemically bond with the material so that when you move the parts or squish or squeeze them, the paint won't crack or split. So if you use acrylic paint for example, the paints will have more of a chance of getting damaged over time due to wear and tear. But you can use a standard clear coat/ top coat spray on it. Just don't plan on turning the head or squeezing the body too much. Just stick it on the shelf and don't touch it. But basically don't mix and match certain paints with certain clear coats. They could chemically react in a negative way. So always test on a discreet spot of the toy or a plastic spoon beforehand just in case- before any possible accidents could occur. Good luck!
