Alclad indeed comes in spray cans. I've been using it the past few years. My first use was the Model King release of the 1979 Ford pickup. I built one of the box art vehicles from a test shot that didn't come with any chrome.
As said the hinges are 1960s design and don't work. They are also hugely out of scale. Look at the hinges modeled on the Jimmy Flintstone A100 van with fixed doors.
I recommend gluing the doors shut, taking care to center them properly. Then take some Evergreen round stock and add non-working hinges to cover the indents on the doors. That's what I did on my A100 pickup.
Cool! We have a red '95 Celica Convertible and it also lacked the rear spoiler. My daughter got into an accident, she got t-boned on the drivers door. I found a red parts car for the door and front fender we needed and it had the spoiler! That one was as easy as swapping the trunk lids.
I don't have a problem going back later and adding a detail or improving something. What I don't want to do is strip them down and redo them. I did that as a kid when I didn't have money or access to enough models. Nor do I sell or give away my finished models.
Yes, it's gonna be tough next year. NNL East is later in the month to avoid Easter. GSL is the following weekend. That means I'd have to leave PA on Wednesday or Thursday! NNL East was two weeks ago and I'm still tired, and the van is still packed! Imagine that marathon next year!
My wife's brother works for the railroad as a track fatality investigator. Yea, there's enough work to keep an entire department busy. When I hear on the radio that someone got killed on the tracks, I know where he's headed that day. And yes, "Deep Pocket Syndrome" prevails. The railroad gets sued regularly, sometimes even in suicides!
Build it! Enjoy it! Irma Bombeck once wrote an essay about the death of a friend. She had to clean out the woman's belongings and found things like a brand new fancy night gown that she was saving for a special occasion and nice candles she had received as gifts that were "to nice to use for everyday". And Irma lamented that those special days had never come and it was a shame, that this lady never allowed herself to enjoy those things. There's a moral here. A few years ago I went through models, resin accessories, decal sheets etc that I was saving for a special project someday... and I thought "I'm 57 years old and I've been saving some of this stuff 20 years". So I broke into it and I've been using and enjoying these things!
I always suggest the guys who want to do a correct beater do a bit of research. Go on the Internet and find photos of similar cars that are rusty. eBay Motors is a great place to find detailed photo sets. Every car rusts a certain way, and photos will give you a good guide how to proceed.
