My methods are a bit different from JetDrivers.
Pull the swing, clean it up real good and the use a good quality wax & grease remover.
Wetsand the existing finish with say 1500 grit. If it's already orange peeled you'll need to sand the dimples out. You'll be able to see 'em once you start the prep sanding.
Use a urethane color & clear. You should be fine sans primer unless you prep to the metal in spots.
Prime if any bare metal, 2-3 coats of color [DO NOT SAND THE COLOR coats], clear coat 2 coats {3 may yellow or not}, wet sand your finish clear, polishing compound & finish with a coat of wax.
I rattle can sprayed my fairing and pods. Color Rite products.
