it has to do more with heat than anything else, i don't think turner accounted for the metal expansion that creates the ballooning / bottle cap effect. especially with the super thin gauge on the end caps... which is probably 26g soft sheet lol

but hopefully your repairs work out in the end!

a very fun and simple video showcasing such expansion.
