If you're having trouble removing EGP sounds like your applying far too much, I had the same trouble when I 1st started using it. I used one of the round foam applicators and apply just enough to layer the paint.
EGP can be layered to give extra durability as a single layer won't last that long. after 4 weeks give it a good wash down and apply another coat, it's far simpler to apply than a wax so just layer it up. A wax would last longer but they don't seem to take to well over EGP, so I'd use just EGP or a wax over SRP
