Default Re: T-cut recipe change

Like many materials, modern versions not only have to dodge ingredients verboten by health and safety, they also have to handle lower levels of knowledge in the general population as well as the trend for instant gratification. A paint surface free of any wax polish looks relatively dull and shows up any oily residues. Including a wax stops people seeing it in this state and makes the after-cutting job look better.

But getting a surface fully wax-free is important if you're going to paint it, especially if you want to blend in an area, and are working with period-correct cellulose paint which will slightly dissolve with the thinner in the new coat. Original T-cut used to leave a slight oily film which you didn't get with Belco compound.
