"""breakneckvtec- I would expect the AIO will remove the NXT.
I really like VM, but I don't expect all that much from it. I'll get the finish as good as I can get it before applying VM.
I've used BFII over VM on the satin black window frames (painted metal) of my XJS, it worked fine, though it seemed to take a while for the BF to fully "dry". Until then it was a bit oily, as if it were sitting on top of the VM. It was OK after a while though.
No, BF does NOT stain trim, in fact, I *use* it on the black plastic trim on my Audis and the XJS.
*I* don't think that either VM or BF hide much. And for me, the abrasives in VM are more of an ease-of-application feature than something that's gonna remove any marring. It's NOT a substitute for normal surface prep, more of a "finishing touch".
I apply the VM by machine all the time. Yeah, use a polishing pad and speeds around 4-5. VM is pretty goof-proof so you can pretty much use it any way you like.""""
Accum, well said, excellent explanation.....
