This must be the reason people have been stripping the chrome and spraying it more often now. I was always wondering about this and your ordeal explains it.
Just do a quicky build or try a new painting style. I have way too many kits I will not build in my lifetime but I have traded a few off for something I will build, well hopefully .LOL
Back in the day most cans had a logo of some kind on them in their own colors. Green would work, or just put a logo on it with your name .

I like your idea about the car hauler . You might want to look into brass angle for your main supports. I have not use it but many guys have done some nice projects with it.
Do not forget that Molds were inventory that was taxed here in Michigan . So if they had no use for the molds in their eyes why pay tax on them. Scrap prices raising when times were tough for the molding company comes out to things being lost/scrapped.
I have two different sizes Frank . If you would like to scratch build some here are the measurements.
The smallest one is chrome plated and is .178 X .268 X .363 Tall .407 to the top of the handle
The larger ones are molded in red ( I am thinking 34 Ford truck AMT) .245 X .350 X .455 Tall .510 to the top of the handle.
Well lets see Tom it was 1984 for me and they still were not cool! 30 years this year and I would buy a clean 73 Pinto wagon if I found one. Yes that is what I got to drive the few times I was able to drive to school as a senior. I was made fun of, but they all piled in when we went sledding with the sleds inside the car.
The other wagon that was in our class driven most every day was an AMC Matador that you could fit 15 kids inside on a Mountain Dew run.
