Ah, thanks, guys! It was definitely a fun project, and a good learning experience, too.
To finish up the thread, I got some shots of the fully assembled and weathered door.
The "metal" trim around the window is just craft foam, sealed and rub-n-buffed.
The trim that runs between the window and the body of the door is one of those niggling irritants - it's supposed to be a double band, but I ran out of time and had to use some single that I could grab quickly.
Some random spray-painted bits from the junk box, bits of dowel, and a few thumbtacks add some realism to the edge of the panel.
Bulletholes, whee!
I love weathering.
And I forgot to take any assembly picttures of the hinges, but they're basically boxes built out of cardboard with a bit of wooden dowel hotglued inside.
But here's the one thing I really hate about this project. You remember how I said that being in a rush came back to bite me? Well, here's how. It turned out that the paper mache and gesso hadn't completely dried back when I was in my sanding stage. So while it was perfectly smooth at that point, over the next week it gradually dried and shrank and distorted, and the end result is the wrinkles that you see here:
ARGH.
Don't let this deter anyone from using the paper mache and gesso method, though! Apart from that issue, I was really pleased with how it worked. Just don't be in a rush like me. If I'd been able to give it enough time to dry before sanding, those wrinkles would never have happened.
