OK, it is clear now that the court thought you had admitted to illegal tinting (notwithstanding the waiver) and that you had removed it to comply. You don't get your costs back for that. You are right, there's nothing to appeal at this point.
Troopers are allowed to be on the lookout for violators. This is called good police work. Make sure your reapplied tint is in compliance with the law.
As for the troopers original statement, he was wrong about that. The law doesn't say you can't apply things above the AS-1 line, it says that stuff above the AS-1 line doens't have to meet the 70% rule.
