Yet it's been stopped by sufficiently solid spells before. You're not seeng my point.
You commented that spells bypass durability when in the item in question is contact with a live target. But it has been shown in the movies that such a rule doesn't apply for similar curses. Curses pass thru weak enough objects just fine to affect their targets. But when hitting solid objects, such as metal, the book specifically states that the spells gets deflected. It also didn't "seep through" anything. We just know that it didn't damage the clothing of its victims but break stone and deflect off metal (w/c would we explained would make sense in certain RL observable phenomena).
And seriously, we don't see enough of the clothing to prove that there was "never an indent". In fact, ppl tend to get tossed back when hit by AK save perhaps for the Sirius Black instance.
