Review on AutoBoxClub FLAG BLACK Transponder UV Protective by John Sharma

So the concept is great and allows me to hide the white EzPass box, I think I saw a review that said the flag disappears. Being creative I decided to just use a clear UV protectant spray paint and apply it in one coat. When I did that, I took off the suction cups, let them dry and put them back on when I was done. Still looks smooth, you don't notice I put a layer of UV varnish on it. If it goes away, now that I know you can put a layer on the EzPass I would just replace it with another sticker and repeat the process.
