I *always* wiped after M205 if only bvecause the oils can dissipate under any LSP and that can leave things looking less-than-great. I wouldn't expect them to mess with the FK1000P's durability but I've never tried it since again, I always wiped when using M205 (which I don't use any more- yuck). I apply it over top of short-lived products and it works fine, zero decrease in *the FK1000P's* durability. It's absolutely not a case where the underlying stuff fails and thus causes the FK1000P to fail; that simply does not happen for me.
BUT- AFAIK, I've only used it over top of synthetic stuff- Kaio, Zaio, 1Z WaxPolishSoft (sorta surprised that it worked so well over that one), 1Z Pro Metalllic Polish, and AutoGlym Super Resin Polish.
Sorry, I don't know from the White Diamond, so I can't address that directly. Wild guess- it'll work OK, especially if you wait a while between the WD and the FK, like a day or two (I waited maybe five days after the 1Z WPS).
