Would treated CD's or OOP's-hold its value later?

The lathe that cuts the edge of the CD polymer has been about 3-4 years old as a tweak. It is yet to early to decifer if it will start pitting the aluminum or not. A few of my old CD's drom early 80's had the aluminum right to the centre of the Cd and have showed major signs of pitting. hence the concern.
I suppose as Viridian explained- there is no going back! That is fine, but will it drop my re-sale value. Take for example Blues in Orbit- Duke Ellington MFSL's 1st SACD ever, is out of print (OOP) and a 2nd hand copy goes for around $70-$100.
What would the market pay if I did my cuts on it, Nespa'd it and used a CD cleaner(the latter two being not physically noticeable).
What would you pay for it? 50% of the value?
Thanks guys for your feedback.

Viridian/Qdrone/Shawn thanks for your insights. I will stick to no modification, as it's just not seem to be worth the extra 5% sound improvement.

Hi Kana,
The reason why I say it is a 5% improvement, as the dealer who used the cutting lathe, nespa pro'ed (30secs) the Cd and then used the Nanaotech fluid on his own Cd copy, of which I have the same, left it with me to audition over a few days. hence the comment on the 5% sound improvement.
On a revealing system like mine (IMO)*. I could comfortably say that the CD lathe flattened the sound- it went to a very 2 dimensional sound.
Then the Nanotech liquid brought the body back and the Nespa-Pro for 30 secs did not make much change.
the recording was a SACD of Ray Brown-Soular Energy (decent quality from the start) so there may have not been much to improve on.
*Avantgarde Duo Omega's speakers, EMM signature combo(CDSD/DCC2-SE) and Wavelength Napoleon's amps.

Osgorth thanks for your suggestion, but I struggle with time to listen. Let alone having to burn them to a CD-R as also suggested by the dealer of the tweaks.
At the moment due to my travels, I am acquiring more CD's than I can listen to. Nice position to be in as I feel I will one day get the time. Hopefully soon!

Kana, you are so right with tweaks on poor soinding CD's. We did the same tweak on the Police SACD and it did lift up the level of red book just short of the SACD quality, but did not have much effect on the SACD layer.
Tweaks do change the sound, one has to decide if the change is more correct in an overall perspective.
My main concern is that I don't sacrifice my Out of print CD's for the sake of sonics.
As Osgorth suggested to play around with a burnt copy, would be ideal.
With the nova physics I feel that the hard drive would eventually be the way to go. Initial trials with other audiophile colleagues seem very promising, and detail can be comparable to top end sources and in some respects could even better on red book.
Always a never ending process!
Thanks once again for your inputs as it makes the thread even more informative.
