ZAIO under FK1000p?

[Accumulator]

I`ve done that combo quite a few times, works well, no issues.

That`s what I do 99.9% of the time...unless I`m just reapplying the FK1000P without doing anything other than a wash beforehand.

I seldom wait for the ZAIO to "cure" (scare-quotes intentional as I don`t know if it really does that) unless I`m putting off the FK until the next day. Never seems to matter.

I`d expect most any AIO to work fine under FK1000P. Even products that "should" (again, s-q intentional) cause issues never have for me; the `93 Audi has Fk1000P over top of the old 1ZWaxPolishSoft, which leaves lots of [who-knows-what] behind. IIRC, the late Rohkh said that the FK works fine over Essence, and there have been other OK combos that I can`t recall...

There was an article years ago call the perfect shine it talked about the whole sealant under wax debate. It pointed out that most waxes have heavy solvents that effected the sealants durability.

While certain combos, even some unexpected ones (e.g., Souveran over top of Collinite 476S of all things!) can indeed go sideways, I never had a wax compromise an underlying sealant. NO, NO...I`m not arguing! And I sure haven`t tried many combos as I consider the whole "wax over sealant" to be a waste of..everything. I`m just saying that it`s hard to predict what will/won`t work, so first-hand experience with specific combos is pretty much mandatory IMO. Fortunately, *somebody* here has probably tried most any combo you can think of

And Setec Astronomy brings up a very good point: Consider the Source.

(I have never had *ANY* issues with David B. I like/respect him. BUT...a) yeah, that article`s old and things have come a long way, and b) he was a vendor and I take *EVERYTHING* that *ANYBODY WHO SELLS THIS STUFF* says with a shaker-full of salt. Oh, one big exception: Ron Ketcham, formerly of FK and retired from ValuGard; Ron`s always been willing to call his own baby ugly when it was; his opinions never changed based on who signed his paycheck, and/but that`s awfully rare.)

Didn`t David`s Perfect Shine Combo use just the KAIO topped with P21S? I mean..and no, I don`t recall from way back then...no wax is gonna compromise cured KSG, at least not IMO, that stuff is a PIA to strip with the proper products when you want to!

Using M16, *via Cyclo* didn`t mess up either KAIO or KSG for me, and M16 has some...stuff..in it that does the "paste wax that turns liquid" thing when applied aggressively.

Eh, Souveran is known to be an outlier, compromising 476S is unusual but it`s known to do that. BUT I`ve used Souveran over top of various AIOs with zero issues at all.

Consider that "Wax over Glaze" was a longstanding approach that seldom went sideways. And/but Glazes are awfully easy to compromise. Most Pre-Wax Cleaners leave some glaze-like stuff behind, but that`s not a problem either.
