MintLP Protractor Issue. Anyone else?


Hello,
I went to use my MintLP Protractor last week to do a re-check of Arm, cause I had dis-mounted the Arm.

Last time I used it, was when I first recieved it, over a good year ago, maybe closer to two years.

What I have noticed with mine, that it was once a frosted transluscent clear overlay over a sheet of glass mirror has now changed.

Now I notice, that clear frosted color of the overlay has turned a dirty brown stained color. Anyone else have this happen?

Whether any other detrimental effects have occured, I am unsure, but this Protractor was always kept wrapped in its protective Plastic Bag, in its Cardboard Shipping Box, it shouldn't have turned a brown color, expecially not for what this protractor cost.

I'm thinking of emailing Yip, and asking why this happened, and what can be done about it? Mark

The Mint LP a great tool. I will say that the only limiting factor to its effectiveness for me is my rapidly deteriorating middle-aged eyesight. At least my hearing isn't changing as fast. LOL.
Mark,

the discoloration I see is definitely under the overlay. It looks like Yip scrapes this material away from the area around the null points, and at those points I see no discoloration. This is why I believe it is not the surface of the overlay. If yours is not foggy looking after using the alcohol I wouldn't worry about it. But, don't do that. Obviously. :-)

I compared the two Mint LPs I still have. The older one that came over 2years ago for the Triplanar does have a copper hue or tinge as compared to the one I received with the Talea(thanks Dan), which has a silvery white background. On second thoughts am not entirely sure if the older Mint was always this way. More important this is, I am sure, a cosmetic difference, and has no effect on usability .
Cheers
I have 5 Mint LP Best Tractor since 2008 and no one of them presents the problem described by Markd51
