Spray door, frame, assorted bezels & flaps with Rustoleum flat black spray paint, then spatter paint with Rustoleum semi-gloss black spray paint. Chill can in fridge so paint thickens and sprays a little "globbier" to replicate the factory spatter.
If your door is good overall except for a few spots, touch them up with Rustoleum semi-gloss black can and a brush, and while the paint is tacky, dab it with your finger wrapped in a clean rag to knock down the gloss finish and blend with the surrounding area. I did this method to touch up a few small scratched areas on an otherwise perfect Pinbot door, and the whole thing look brand new.
