NICE WORK!!! If you print posters - SIGN ME UP for one!!!
When I was doing my car, I did screen capture JPGs from a LOT of scenes in the movie to get my door star right and the P1's... Problem is that they used so many different cars for so many of the scenes, that no 2 really match perfectly. In the drawbridge scene, you can see that the right rear door handle is missing (and white paint is showing) and in some scenes there is a hole in the driver's side rear quarter panel where perhaps a whip antenna may have been?
Pay attention to the P1's and the door stars in the movie especially... I can't remember the scene, but in one instance they look like they were done by hand with just a can of spray paint and no stencils or tape!!!
I just drew up some P1's (and my door star) in AutoCAD a couple of times until they looked and fit right, plotted them out on big paper, and then cut out the letters and held it to the door with a LOT of refrigerator magnets (to make a cheap stencil). LIGHTLY mist your P1's with gold spray paint and then clear coat it so that the paint doesn't wash off (don't use a GLOSS clear coat, and yes the spray paint WILL fade in the sun and will wash off if you don't clear coar it! I had to re-do mine twice before I realized what was going on).
I did the door stars the same way (cheap stencil & magnets) and painted the star a little heavier with gold first, and then did a sloppy job of covering the gold with black spray paint. Again, there are very few scenes in the movie where the stars and P1's look the same!
