I have had success by using a much larger than needed piece and stretching it carefully over the part being "plated". Dog dish caps for instance, I will take a 1" square piece of BMF drawn tight and press the cap into the foil carefully so as not to rip the foil. I have had limited success with this same process on bumpers and other sharp turns of wheels and engine components.
If you want super quality, send your parts off to be plated. by far the best way to get a chrome piece with a flawless finish.
