As I've been noticing that numerous small scratches and rub-marks have been accumulating on quite a number of my framed prints plexiglass glazings...I'm looking for ideas/recommendations/resources for repairing these defects if possible, as I'd like to avoid the costly process of plexiglass replacement.

While it looks like many of the defects are quite shallow, and might lend themselves to being buffed/polished out in some way...there are other scratches which are a bit deeper, and my thought is that there might be a product with which one could fill these scratches to make them "disappear."

At any rate, if anyone here has any knowledge that such plexiglass repair might be possible (fingers crossed!), and might also point to some resources for this...that would be great. Thanks!
