I agree it is nearly impossible to spot toner. That's what caused the main issue. I was having mild smudges on the surface, which I figured I could smooth out and re-tone, until it became more and more visible.

I ended up sanding most of the surface down, but having lost most of my toner in trying to fix up, I had to use the contrasting color to finish the job. It looks somewhat OK and will do for now, but as stated earlier it is scheduled for a redux as soon as can be.


This is what I had at first:
   

See the blotches? What was the cause of that? It was appearing only on a select area of the front of the radio. Did I mis prepare the surface?
Once I sanded down and retoned, I started to have visible contrast at the edges, and the toner leaked a lot more, like it wouldn't stay on some of the sanded areas. Not very good.

this is what I ended up doing
   
not too bad in the circumstances. As I said, it'll do for now.
