I cut this one in the early 90s (maybe 15 or 16 at the time). Put in a POS Pioneer CD.....
Tack welded a backer....
drilled holes in the backer to rosette a paper thin filler
small amount of glazing in the seam and some primer. Its not 100% perfect.....BUT REALLY CLOSE! I still need to do a little more work on it but it should be undetectable that it was ever cut when I am done.
This thread made me laugh because I spent a fair amount of time (sort of an obsurd amount) undoing what I did when I was younger.
Good luck to anyone that tries to 'uncut' a radio delete.
