paint help please

[YOUNGY]

i'm going to spray the chorome rear bumper for the escort in 2k satin black. Obviously i will flat it right back just wondering whether to use zinc primer or etch primer or is there something else?

 

Many Thanks paul

Put a coat of etch primer on then a couple of light coats of 2k primer on then wet flat it without going through the primer and it'll be fine
