I do as well use FK-425 after waxing. I also use FK-425 after I am done washing the car. It really helps in the slickness of the paint.
Same here, but I have had *one* instance where I ran into the sort of issue that
mikebires is concerned about.
In that *one* instance, I spritzed FK425 over fairly fresh (applied and buffed a few hours ago) 476S. I got very light, smeary effects, apparently from a solvent action that the FK425 caused.
Note that the vehicle in question had *severely* compromised paint, early-stage cc failure, checking, and pitting you wouldn't believe. It's my opinion that there was an excessive amount of "extra" wax trapped in the not-so-micro fissures/crackes/pits of the paint and that the FK425 softened this extra wax up.
On the sides, which were in much better condition, the smearing was minimal to nonexistent.
Extensive buffing with distilled water spritzes and CBTs cleared *most* of it up, but had the situation been different I probably woulda rewashed it.
But again, that was the only time this has happened out of *many* FK425 final steps, and I just *gotta* think that the messed up paint played a pivotal role.
