Around here they only care that the holes are filled/patched and not jagged. Sure, they can fail you if it's literally rusting in half but that's a judgement call and they never do that because there's no money in it.
It's not about safety. It's about giving some mechanic leverage to upsell a shitty bondo job where $5 tape will do.
Wish vt wasn’t so critical, metal must be welded. Blah blah blah. but not having an inspection sticker isn’t an offense they can pull you over for break one law at a time.
