The easy way of tinning self fluxing enamel is to apply iron tip and fresh ?cored solder to the cut end of the wire. The solder reacts with the exposed copper, the ?coating then melts back and the exposed copper tins quickly. Practice is good BEFORE you do the important stuff.

Scraping works well, you just need to remove a line of enamel -not remove all of the enamel- before iron & fresh solder. ?A hot iron helps a lot for tinning .
?
Note that there are some coatings that are NOT solder through, such as deflection (scan) coils or high voltage/temp ?enamels.
