I have the same issue. I will just be sanding mine smooth, not necessarily to bare metal. The good advice above will get you to a like new finish. The rest of my truck is not like new. I will be using the Rustoleum products that you thin and roll on with foam rollers. My roof is white so I will probably tint the white paint to get it close to my factory color. Roll on the Rustoleum primer, roll on the paint. Wet sand it a little, buff it, and call it good. Will be the nicest part of the truck but will fit in better than a perfectly glossy new roof and will be a good base if I ever move past the patina/character mode and into nice paint.
