You need an etch for alloy or a etch and primerin one (suitable for alloy) then sand and paint as normal.

so you spray the etch primer on and sand it off

No, you spray the etch and paint straight over it. A pity you sanded all the black off because it was most likely etch primed underneath and would have served quite nicely as a substrate.

Etch primed the forks today , turns out i left some black paint on the forks and the etch reacted with it , so it put some paint stripper on it , then recoated in etch 3 times. Painting them tomorrow.
