You can try getting it out on a buffing wheel. The buffing wheel is wearing down the problemed areas which results in the shine. If you used CA to repair your acrylic then an adhesive specifically made for acrylic should have been used instead. I think the stuff I used at one shop was called Acrylweld...it's been awhile so I can't be sure. Regardless, just ask for something specifically made for acrylic. It dries fast with no trace.
