I agree with Whale you are up for the cost.
BUT
If you obtained approval to install the tinting (from EC or OC) by having a ordinary motion passed and no bylaw or conditions were included in the motion, then you have the strata permission and as their is no acceptance of ongoing maintenance from yourselves, then it would the the Strata problem to restore the tinting IMHO.
This to me seems a huge problem with strata law in NSW.
