I have several Alan Bean prints and other presentations mostly framed in aluminium with the plastic UV protected glazing.

Now, I don't know why, but this glazing is very easy to mark or crack. Today I accidentally touched the corner of one print with a cardboard box, The actual corner of the box had worn down so was not a point. It was just the lightest of touches, but it has marked the glazing.

I have had this happen in the past, with similar just minor touches and this glazing just gets so easily marked. It's proving to be very frustrating.

I wonder if anyone can advise on a method of removing the marks. They are basically scratches on the surface, about a hair's width.

I will never use this glazing again, I know plastic glazing is more vulnerable to some respects as glass, but this just seems to be extremely fragile.

When the framer did them, the first time he used this glazing. It came with a protective cover, and simply removing the cover would mark the glazing, he had to replace glazing for a few of these prints. He said he would never use this type again.

Any advice would be appreciated please.

Not sure if all plastic (acrylic) are the same but I have never had an issue and I have over 100 frames in the house that use UV acrylic.

I would suggest reaching out to the people at American Frame as they have always been more than helpful to me and could suggest the best method for restoration.

Thanks for the reply, I feel there is more than one manufacturer. I want to try and track down the manufacturer of mine, and find out what they have to say. I really should have done that when the framer explained his problems using it. It's a long time ago since they were framed.

NOVUS is the best stuff for that. I've used it on my Speedmaster, my signed TMC models (that acrylic cube they come in), and on various acrylic frame glazes. This is also what American Frames sells on their website for care.

Thickness and temperature extremes, some acrylics hold up better in fluctuations in temperatures better than others. Extreme cold is never good for those polymers, whether acrylic or O-rings...
