I never used EX, but it sounds to good to be true. It's a sealant that can be applied on top of carnuba waxes, excellent shine, and can be purchased in gallon quantities. I'm sure I'll be ordering soon, just trying to figure out what combo I'll be using with EX.
Here's some possiblites:
1) vanilla moose + EX + S100
2) GEPC + EX + S100
3) Poorboy's Polish w/ carnuba + EX
Which combo sounds best?
