The wax was always the problem with T-cut. It was the devil to remove if you wanted to cut a paint finish for re-painting. I used to use ICI Belco medium rubbing compound, but you can't get it any longer. What you can get is a range of grades of Farecla cutting compound. Done by hand, it's tediously slow stuff because it's intended to be used with a machine. Number 3 cuts moderately well, 6 is general purpose, and number 10 is needed for getting perspex glittery. On small things like radio bits, machinery is impractical so it's a lot more work than it used to be.

One of the uses of cutting compounds is to remove years of build up of wax or silicone polishes and muck. Ideally you want to remove everything to a clean surface, and only then do you want to apply new, clean wax. If your cutting compound contains wax, then the dirty old stuff you're trying to remove mixes in with the new wax and is kept on the surface. You dilute the dirtyness, but you don't remove it very efficiently.
