I have a can of it but really can't find a good item to use it on. My cluster is A-O-K as is the wifey mobile.
I think it's a great product from what little I've been able to play with it. I use it on my heads/corners/tails and it really does seem to add a protective layer.
From the standpoint of removing scratches and such, I think I'd probably lean towards the Meguiars clear plastic polish. I know the Porsche guys SWEAR by this stuff for their rear window which is a plexi-glass type of material.
