I have a brand new (NOS) slipfitter I'm planning to use on a new setup in the near future, but it's currently powdercoated black, and I would like it to be green instead. What should I do to prep the surface before I paint? It's shiny so I know I need to do something, but I don't know if primer would be enough. I'll be using spray paint for the final finish.
I'd appreciate your advice!
