Hi,
What do you mean by autoglym gold? Do you mean extra gloss protection?
If it was me, I would assess the condition of the paintwork on arrival and if it was "swirled", I would consider having a conversation with the dealer about the standard of their brand new cars!!
If it was only midly swirled, I would give it a mild hand polish with autoglym super resin or similar (your deep shine will help hide swirls), but primarily I would be looking to put some decent wax on there, collinite etc.
If your feeling flush, now would be a good time to get a decent detailer to correct the bodywork (as very little will need doing, making the job cheaper) and seal it for you properly.
