I knew a guy that had a rear bumper made out of wood on his old Ford...he painted it black and drove it like that for years and years....
One of my best friends 'builds' trucks, usually Chevys, Jeeps, and Nissans.
He usually starts with 3, ends up with one good one, another that can be repaired, and one for scrap.
He does good work too.
A few years back he had a really nice mid 90's Nissan 2wd truck(made from 3, lol).
Everything was good, except one bad place in the frame.
It wasn't to the point of being structural problem, but was near the gas tank, and more trouble to weld at the time(which he later fixed correctly), and he needed to get it inspected.
I came back a couple days later, glanced down through the rear fender well, and looked at what appeared to be a beautiful repair, as it never had rusted, and no suprise really either.
He laughed, and told me to look closer, which I did.
I said, "Did you swap the frame, I don't see any welds?"
Nope, I used metal hvac tape to cover the hole, and then undercoated the frame, lmao!
I had to crawl under and look at the inside of the frame to see the hole.
He told me he was kind of disapointed too, as the inspector never even looked at it, lol, he just checked the lights and put the sticker on it.
