@atronach: i just checked the gw online store, and the black spray can is there...my lgs has it too...the main confusion could be from the fact that gw calls it\'s white primer*drumroll please* white primer!!!, but they call the black primer chaos black...it\'s in a blue can with a black lid...
when i lived in the third world, all i could get was car primer...seemed to work fine for 25% of the price...i got the grey, sprayed it, and then painted my usual layer of black touch-up over it...sorted...
can only remember usin\' the brush-on primer once, when i was in dire straights(no not the band)...worked fine, as far as i can remember, but it did take a lot longer...don\'t know why gw calls it smelly primer, as all paints smell funny to me...
cheers
