“It does suck, because everybody kind of makes fun of the Cybertruck. To the outside person, it’s kind of weird, it’s ugly, whatever. Once you actually get in it, drive it, you realize it’s pretty frickin’ cool,” he says. “It’s kind of been sad, because I’ve been trying to prove to people that it’s a really awesome truck that’s not falling apart, and then mine starts to fall apart, so it’s just… Yeah, it’s kind of unfortunate and sad.”
Epoxy bonding on body panels is super common on many cars now. And it’s the only way to bond incompatible materials like aluminum and high strength steel.
Even steel body panels can’t be welded to high strength steel because the heat affected zone will be weakened by the weld and will crack just outside the weld.
Adhesives to create a mechanical bond, and the 3M body adhesives include glass microbeads that prevent you from squishing the joint too tightly, which makes the bind more effective.
Now using it in dirty or coated stainless steel clearly isn’t working, and the design of thin strips of shiny steel that will grow and shrink a lot, mostly in one direction on a design that was done by a 7 year old in a hurry to draw a truck is another issue.
Good points.
Why aren’t they using fasteners? Cost or weight?
