If you use this put on two layers because one looks more pink than red.
Heres some pics.
There were three of these and they all looked the same.
Before tape.
The tape I used. Notice how you can see through it. Kind of pinkish.
I laid the lens down and stuck the tape to the back side of the lense.
Using a singled sided razor I cut the lens out of the tape.
Pretty good I think.
Finished product.
Conclusion.
The tape seems to work good but in the long run who knows.
