paint not sticking

Alright, i'm trying to paint some exterior plastic pieces off of my truck but am having a hard time ven getting the paint to stick. Here's my procedure......Scuff with geay scuff pad ans scuff stuff, let dry. Clean with waterbourne wax and grease remover, let dry. Spray one coat of adhesion promotor on (spi) let dry then do a second coat. Then spray a coat of epoxy on let dry, then when i shoot on my base it starts to lift and if i dig it with my nail the epoxy is super soft and rubs right off the plastic. whats going wrong?

kinda a crazy thread you got going here ,, one post exterior, the next post interior .

If one were to reverse engineer a way to make paint not stick this screams it...

I couldn't leave it alone, . .sounds like to much of everything piled on there that scared the paint off.

my bet is what ever you call adhesion promoter just rolled up under there...

Anyone notice he's saying his EPOXY is super soft? That tells me he is either not mixing his epoxy right, not allowing enough flash time, or the adhesion promotor is not flashing enough before he puts on his Epoxy.

Although, why are you putting Epoxy down on bare plastic?

I'm using all spi products. Their "plastic adhesion promotor" and their epoxy. It even says right in their tech manual for best long term results to apply a coat of epoxy over the promotor.
