Tube repairs

[CSR]

Hi all,
It's been a while since I've been on this forum as I sold my rib a couple of years ago but I got another one last week 👍👍👍👍
The new rib has no leaks and is totally airtight but there are marks on the stern where the stern line has rubbed through the rubber onto the fibres. What's the best way to fix this? Someone told me today there is a paint that you can get to paint onto it.

People here generally don't like painting tubes. (Ugly, short term fix).
It sounds like a wear patch would be a good fix. Probably with a matching one on the otherside so it looks like it was designed that way.
