99-00 Fender Painting help

[Riverwalk]

Hey I recently just an aftermarket oem 99-00 fender and it comes in black(metal obviously), How do i go about painting it? Do I need to sand/prime? or just go ahead and paint?

Also gonna get a mugen lip(replica), its made from Poly Urethane, what do I need to do before I go about painting it?

thanks

The paint shop should know what to do. Unless you don't want quality work....

take it to a body shop

Oh I plan to do it myself cause i do a lot of paint jobs on primed bumpers and etc but never worked with PU and fenders.
