What do you think is in this wax? I have never seen anything like it. Although I mention Gallium wax, I am pretty sure it's not that, even though I have never used or seen the stuff.
I came to the conclusion it must be remelted wax from scrapings out of a ski shop where grinding particles were heavily mixed with the collected scrapings. What do you think?
After good scraping and brushing all I could see with my eyes was gone.
