amonia??? whats wrong with water? its cheaper, maby?
well i would say to pull that part of the sheeting off and try to reset it.
if you uses a water based glue soke it up with water and the sheeting should come up easy after a few minutes, if you used CA get the exacto out and hope you dont mess up!
to reset the sheet try to get it all down using water, there might be a slight curve on the edge but it will be flat, get it really wet and clamp it/pin it to follow the curve until dry then unclamp/pin it and glue it down.
there may be other ways to do it but this is what i would do, and youre not me...
