@Kim-Rosenlof thank you very much for the video link. Unfortunately, I searched all the webshops in Norway and could not find the touch-up texture product. It contains some kind of chemical that is not allowed for international shipping. So looks like I will have to wait for the next change traveling to some other countries to get this product.
I would be so nervous to use the scraping method, hahaha... But maybe I will try it, because why not?
