Very, very kind of you......

Thanks so much, Mike. Very generous of you to offer. :-)

Actually, I have about 9 CD Greenbacks left myself, as well as the very cut-out I described for the troll in my other response in this thread. I used that cut-out to try the Dark Matter on the tray initially, and found the combo to be very good. But actually painting the tray a few days ago seemed to give the best results of all, which would indicate both that the CD Greenback's color is not perfectly optimized for that application (still, a BRILLIANT idea by old Uncle Stu!) and that using multiple colors in the blue-green range (cyan, aqua, turquoise, light blue, etc.) is likely the most effective approach when using color to absorb jitter-inducing stray laser light..

Dark Matter is a great product, but again, it is not completely optimized for that application. Why? Because the DM will inevitably degrade over time and usage. That's it nature. As it works, it is used up, and likewise, when it is exposed to UV from ambient sunlight. It's the nature of the beast. Moreover, DM must be reapplied every so often, and the more that is used, the better the effect. Paint, on the other hand, is permanent.

Thus, my desire for an optimization approach that combined both painting and DM for the highest amount of jitter reduction possible.

(Or maybe I should simply do as a brilliant EE friend of mine suggested just yesterday when we discussed this very issue: go computer audio, get bit-perfect copies free from jitter and be done with it. VERY tempting, I must say at this point.)

Lastly, thanks so much for the suggestion about polyurethane spray. Yeah, I had thought of that one, and the yellowing was obviously a problem I also anticipated (thus my caveat in the original post that any such application must be 100% transparent and have no color whatsoever.) My ex-wife was an artist and art teacher, so I was quite familiar with polyurethane as preservative and its limitations. But your offer of help is very, very much appreciated, Mike. Many thanks for your time and efforts on my behalf. Cheers!

I simply cannot think of another coating. I will call an art supply house here in NZ on Monday and see what advice they can give. If I find out anything that could make this work, I will definitely be happy to share with my fellow 'philes here in the venerable Tweaker's Asylum.

Because the combo of DM and multiple blue-green paints on the tray should be a real winner (until of course, I finally go to a computer-based audio playback source..... )
