Ultra Deep Shine and Super Resin Polish are quite different. UDS you cannot top with the Extra Gloss Protection (and its for this reason I am not a fan) as it was designed as a stand alone product... SRP is lightly abrasive, better at overall correction and can be topped with EGP but on its own offers less protection than UDS.
When topping with Meguiars wax, be aware of streaking as a product which is not bonding to what it below it will leave streaks... UDS I have topped with a carnauba wax quite happily, but a sealent style product will not be happy over it in my experience.
