the megs deep crystal paint cleaner is pretty good to be fair, would polish after it, then a glaze and any lsp you want.
my 2p would be to get some applicator pads, a few mf's and a bottle of glaze (very partial to the clearkote one at the mo myself)
What your using wont give you a finish like some of the folks on here - But ask them how much they've spent to get the products they have.
Also Guy 7 quid for 500ml is about what cw&g costs, that stuff dilutes very well.
ring a few local valeters, see what products they use, and if they'd sell some samples?
Or ask on here nicely sure someone will be local let you have a go with some products
