Some chafing pictures:
First the top edge of the scuttle:
The touch up (a Fiat yellow) is a closer match than it looks here, but you'll see in the next picture why it doesn't matter.
My solution after a bit of head scratching is a leather patch on both sides. We'll see how that goes. Secured with double sided tape.
Here's the body under the doors:
This is not uncommon, and you need to check your car regularly here, although my Roadster doesn't chafe here at all.
The door bottoms were also down to the alloy, here I've blobbed some etch primer on, before top coating. You can get away with taking liberties down here because it doesn't show. It's not worth too much effort either if it continues to chafe.
This next one shows the sealant on the bulkhead, which I've now tidied up.
