I'm confused....I dunno why you would reseal before you reapply a wax
Once you put a wax over a sealant, you can't apply more sealant without stripping it off and starting over.
Claying may/may not remove the wax/sealant depending on how aggressively you clay (I clay all the time without compromising my LSPs; I spot-clay as needed at every wash).
If you put a wax over your sealant, just clay *very* gently with something like Sonus green Ultra-fine clay and reapply the wax. Reapply before it's really necessary and you'll probably be able to do this for a long time....until you get enough marring that you want to polish it out anyhow. That's what I do; I hardly ever do anything except clay and re-LSP.
But then I don't put wax over my sealants as I like to add *more* sealant from time to time.
