I've done the same with my RX8 and found brilliant results! Cannot fault with Meguiars! So much better than Autoglym. If you clay it and use quick detailer, its even better!
i would deffinatley reccomend 'smartwax' wax, iv used all sorts of products in the past and this is deffinatey the best by far, very easy to use, leaved no white marks, can use in sunlight and doesn't dry on. and gives very good results, in fact i would reccomend the whole smartwax range.
