Puterbum,
ZFX?? What are you, the prodigal son?? Back to Zaino now?
I've tried Zaino over
AIO with no (apparent) problems. But I can't be certain as it was only on there for a couple months.
BradB. I am simply amazed that you are able to use Finesse It (by hand I presume?) on a red car and get a marr-free, glossy surface. I've tried FI-2 and made a complete mess on my black bimmer. Just goes to show how important technique is.
