Interesting project, thank you for sharing the setbacks as well as the triumphs.
Back in 1982 I installed a large sheet metal chin spoiler under the front wood bumper of my 1976 Ford van. I used a rubber garage door seal along the bottom edge. It worked and looked great.
The drunk who lived next door decided to back into it one night and bent the heck out of the spoiler. I was 20 something years old and mad, I kicked in his doors when I saw what happened. My parents were very concerned and told me what I did was illegal - my response; SO IS DRUNK DRIVING!
Don't ever do what I did, just saying.
Others are using conveyor belt material from places like Tractor Supply for the chin spoiler material. It's kind of heavy but wears gradually.
