I would scuff it with Scotch Bright the finer ones and spray on DuPont Adhesion Promoter, then the color you want. If the finish color is a DuPont product then it is better.
Just my Opinion.
When I did mine, just painted it that is, I scuffed it getting all of the open areas and found it was more trouble than it was worth trying to get in the holes, so I sprayed the Adhesion Promoter as it was, then the Black Paint, DuPont Paint...
