Question 1

Will this work without direct sunlight, on a window that's under a shaded patio?

Accepted Answer

I believe it will - it worked for us on a row of windows under an eave.  The principle is that the dots (that's how I used it...as dots on the cross-hatches of interior mullions, so cannot be seen from inside the house) are visible to birds although not so much to us - if enough light to cause a reflective surface generating bird strikes, there is enough to 'shine' ultraviolet for the birds.  Was 100% effective in our application.

Question 2

Does the liquid last longer than the decals? Also, is the liquid effected by washing the window?

Accepted Answer

No, the liquid does not last longer than the decals, but it does last for several months here in Arizona.  The decals last for a few years.  I just reapply the liquid each time after I wash the windows and it works just as well if not better than the decals.  It goes on quickly and dries in about a minute and a bottle goes a long, long way.  It doesn't interfere with my view in or out of the windows, but at certain times of the day, I can see what I've drawn on the glass from both sides.  I recommend the liquid and will buy it again to use together with decals.  Not a single bird has hit the windows since I started using them.

Question 3

Does this product work on mirrored glass windows?

Accepted Answer

I don't know whether it works on mirrored glass, specifically.  The liquid should be applied to the exterior surface.  I just refreshed my 'dots' for the season and added some new stickers and haven't had a bird strike since the refresh.  It's been easy to tell when the effectiveness wears off; unfortunately we start getting bird deaths again.  I recommend a twice a year refresh.

Question 4

I know it's supposed to be applied on the outside, but will it work if i put it on the inside?

Accepted Answer

No. It needs to be on the outside to break up the reflection on the glass.
