took my coupe for a hand car wash today i knew it was dirty ....... but what a difference .... its a moonie now were before it was a dull grey ...... going to have to keep on top of this as my coupe now looks the dogs bo**ocks ...... anybody now of a good polish that i can use

Turtle Wax Ice, easy on, no white marks, and easy off. Lasts well too.

Can't go wrong with Meguiars, once you have polished get a good wax on it.

I have found that ice stuff extremely bad. Always found autogleam stuff very good

You have a Silver Metallic so require a different wax/sealant to most of the other colours. See here. I've experimented but always come back to Car-lack 68 sealant and then a coat of Collinite's 476s. The great thing about the sealant is you can just slap that on and forget the wax when it's winter and still have complete protection and a decent shine.
