Stripping Mr. Super Clear from vinyl

[Fat Brian]

My wife is building a small ball joint doll and her torso is made of soft vinyl. In order to color her body appropriately you have to seal the vinyl and the best thing going is this stuff from Japan called Mr. Super Clear. It acts like a spray acrylic, the vinyl isn't sticky afterwards like if painting with a laquer or enamel. The stuff is awesome and I use it on armor models for coating rubber tracks before weathering and as a barrier coat for thinner-based washes. Anyway, she needs to strip this stuff off of the vinyl torso but what would break this down without eating or otherwise disfiguring the vinyl?
