Your avatar photo looks exactly like my vehicle, 0327, looked when I got it. All white, faded, with it wearing off in places and the black paint showing through.
40 hrs of sanding, wow, you've got patience and determination! For the rubber, take a look at Soffseal:

They'll send you a catalog on request. I got 0327's rubber parts from there and they were fine to work with.
Good luck!
