I would think acrylic isn't at all like an auto clear coat. I am sure most car clear coats are enamel which is much harder than acrylic. Just as billy Z said test it well first. But I honestly don't see much of a problem with it as long as you could buff it out well and apply with a very soft clean cloth. Try it on a test piece or section and let us know...
