Does anyone have any more restoration tips?

I would like to rechrome(sp?) parts of the front grill.

I found that metal polish works pretty well on the grill to restore
luster. Don't use it on the chrome or on the door handles:

How does one restore the blackness to the door handles anyway?

What is the deal with the rubber window bits? Any way to spruce them
up short of replacing them?

Headliner cleaning/replacing?

TIA
