I've used Armourfend
You do need to use an approved installer... Morgan at the factory only trust 1 person to install on the Aero's!!
Cost varies... There are set patterns and should come as a set.
It wil always be visable and will become more so over time.. the Armourfend can go slightly yellow over time. Defendall from what I have heard is not so bad.
Also.. if you use a regular polish or wax that leaves white residue (carnuba wax does not) then you'll get a white frame round the film if you are not extremely carefull.
It can begin to lift at the edges which is not ideal...
Stone impacts can chip the paint under the film.. which if you ever remove it can pull the paint stright off.
You don't have to re-apply until you either get a dent or it becomes tired looking.
It can scuff on the surface of the film.. you can see this on Aero's under the door on the running board (usually a popular place for catching heels for example).
Youre probably better off getting a decent Carnuba based wax 50% or better and using that. Carnuba wax sets like concrete, can be refreshed every year (no need for interim applications) and will never tarnish like the film does.
A lot of performance car owners use it to protect the paintwork on track days.
