Wait, wait, wait.
I use Zaino-exclusively-and it leaves a white residue exactly like all other waxes do.
It is everywhere. In creases, at the edge of rubber pieces, anywhere you dont get it all off!!
The clear bra provides miles of edge for the Zaino to leave the white powedery residue. And it does leave a residue.
I use Z2/ with the ZFX accelerator, with a Z6 gloss enhancer between every coat. I am up to 4 layers of Z2 and 1 layer of Z5. The stuff is awesome, but I do not know why you guys don't see the residue on the lines :?: .
