Hello!
Its a bit confusing, this isnt anything against you personally but there is alot of confusion on here to do with glazes.
A while a go, people did put a glaze on top of a car at a show etc. It something that washes away quickly in the rain and just isnt the sort of thing people really do anymore.
If your intreasted in getting a bit of jazz post LSP why not get one of many quality QD's or spray sealants/waxes.
Further more the glaze people used was different, it was #7 show car glaze, its unique in that it doesnt haze, it skins. Its special and different to any other glaze you can buy.
With regard RMG, its an oil based glazed that by hand will will not remove any defects nor will it remove your LSP.
Its best qualities are that it enhances metalic pop with a light, ice wet rather then flowing wet (what i call faux or fake) finish. In order to get these benefits it needs to be in your paintwork. Your paintwork is porus and thats where it needs to be, pre LSP.
RMG and polymer products do not mix really. Now you could use RMG under WG that is amazing esp. on silver.
Apply RMG on top of UPGP if you want to, all you will find is that you move about the glaze and then dries to a red dust. It doesnt skin up like #7 its totally different.
I hope that helps!
