dear wajid bhai
now mashallha u learn tech of shampoo wash, drying, waxing, buffing out, detailer spray concept, now u ready for pro approach
as usman bhai suggested more natural oils means "glazes" glazes cleanse the paint and rich oils penitrate into paint skin and enrich them with very deep, wet look, its colour darkning formula and pull out miracles specialy in dark paints , glaze dont have its own life so have to seal it with wax
since u using megs gold class wax so recomand u megs mirror glaze #7 , u can source it from shahid auto and by giving ahsan bhai ref u can get discounted price.
after shampoo wash/dry, apply this glaze panel by panel, since now a days cold so best time is to apply in sunny day under shed, apply very thin and give massage and wipe out with clean microfiber , dont give hazing time as otherwise bit difficult to buffout.
than top up with ur car wax, trust me u will notice day and night differnce inshallha 
paa gee menu guru bol ker real gurus de bisti na karo , i am also same like u learner here on this thread from big guru gee v1 dear usman bhai
