Default copy chrome and aluminum problems

I'm trying to plate aluminum with a copy chrome kit but I'm having problems
it's coming out of the tank looking like sand paper once I dry it it starts to delaminate
I have tried all kinds of different amp settings and it's still happening
solution is not contaminated because everything else comes out great
(coopper pipes and metal)
the last thing I can think of is the zincate cuz is the only thing aluminum use that others don't .
is there any special way to zincate it ?
I just dip the part and after 2-3 minutes the part stops bubbling and I take it out and plate it.
any ideas
