Wax should always be applied after Sealant. Extra Gloss Protection (EGP) is a sealant, and really enhances the shine of Super Resin Polish (SRP).

Try Wash > Dry > SRP > EGP. 24 hours later, add another coat of EGP. 24 hours after than apply one or two coats of Gold Class?

I used to use the EGP, now switched to the Jetseal 109. Very easy to apply and seems to last better. I've got two cars done now, one with EGP and a coat of Swissol (or Swissvax as it is now) Saphir; the other is jetseal109 and collinite as was recommeded for monster longevity on detailing world. The collinite lasts marginally longer than the saphir but the jetseal easilly out performs the egp.

What is the Jetseal 109 exactly and where can you get it from?
