There is no way to remove the tint from the glass except to replace the glass with untinted glass. The only alternative to getting the same benefits of window film is to install window film over the factory tint.
Parylene N and C have a low degree of crystallinity; however, parylene VT-4 and AF-4 are highly crystalline ~60% in their as-deposited condition (hexagonal crystal structure) and therefore are generally not suitable as optical materials. Parylene C will become more crystalline if heated at elevated temperatures until its melting point at 270 °C.
