Looking for an audio clip repair plug-in

Hello fellow Sonarians,
 
I have some songs I "mixed" in the days when I didn't know that 0 dBFS was not the same as 0 VU and, of course, some of my mixes are clipped.
 
I think I remember reading about, seeing, plug-ins that can help repair or at least mitigate this problem?
 
Any ideas/ recommendations?
 
Many Thanks,
Ray

In my experience,
It depends how bad it really is. I've tried these plug ins. They work okay for certain things like narration, vocals.
 
Mixes= forget it
Multi track= if you zoom in close enough you can cut the clip out and sometimes it is barely noticeable.
 

I have iZotope RX6 (deClipper) - but this has never worked on clipped audio.
We digitize thousends of tapes and vinyl and have never found - in 15 years - any tool that repairs clipping in analog or digital recordings. The result is always unusable.
