I don't think so Scratch-X is a polish/smr so it should not interfere - I have used VM under EX and Wolfgangs and had no bonding issues so you should be fine.

WG (and probably EX-P as well) are loaded with oils and fillers. I don't think either product is actually bonding to anything. Putting them over scratch x isn't really a big deal. You're not affecting durability since there isn't very much (7 weeks for my WG, can't comment first hand on EX-P)
SG is true pure sealant. It needs a clean base because it actually does bond.
I would always use AIO before SG for best results.
