the glass will be easy to fix. unfortunately not for the poor old plastic bits. the more of that stuff you put into it, the more likely it will crack in the sunlight.
go to a panel beaters workshop, (if you can still find any-thanks NRMA) and see what they use. if they are worth their sweat, they wont be using armourall. they will most likely be using a quality product like autoglym or mothers.
it all depends on what your overall aim is, to keep your vehicle looking good and to keep it for a long time in that state or if you are just trying to make it look ok so you can sell it to some poor bastard who will probably have to look at replacing the dash and door trims etc.
